I think in the absence of manufacturers' updates, QuickLOAD still uses Explosia data as today's Accurate and Lovex default values often appear to be the same.
Also, Accurate 2520 has an identical printed table for the Grendel in the former Western Powders reloading guide to its table for Ramshot Wild Boar which is definitely a Belgian (PB Clermont) made grade. The two are the same right down to the bullets used, MV and pressures to the last unit of fps and psi. Nevertheless, Americans on another forum assure me that 2520 is labelled 'Made in USA' and comes from the former Olin, now General Dynamics, St. Marks plant in Florida. So, these ['Accurate'] powders swap and switch sources around it seems.
However no Accurate grades are made by Explosia (the Lovex manufacturer). If extruded, they're made by general Dynamics in Canada (which also makes most IMR powder grades); if ball they're from St. Marks, possibly PB Clermont in Belgium at the margins. (All Ramshot grades have been from PB Clermont, at least before Hodgdon bought Western Powders out recently.) Hodgdon has a very close relationship with General Dynamics St. Marks, so one would expect further developments from that source which might see changes to former Western Powders products in the coming years. We get Ramshot grades directly from the Belgian factory thanks to Henry Krank, but no formerly Western Powders / now Hodgdon 'Accurate' grades come to us from the USA.
The sticker at the bottom of your bottle is a reference to the pre-2004 situation where Explosia in the Czech Republic supplied most Accurate grades including 2460. When Western Powders took the former Accurate Arms operation over in 2004, it changed suppliers to General Dynamics whether Valleyfield in Quebec Province or St. Marks in the USA and hasn't bought any Czech powders since. Here and elsewhere in Europe, the same powders as before continued, but now renamed as Lovex D0 or S0 numeric grades. To let people know what they were buying, the Lovex grades here at least had 'Formerly Accurate Whatever' overstickers added by the distributor. Western Powders wasn't at all happy about this seeing it as a misuse of their trademarked product name and substitution of their product. As it seems it couldn't stop the practice, it put the warning to European handloaders up on its website. As the 'new' (Western Powders provided) Accurate and 'old' (Explosia manufactured) Accurate powders are reasonably close in charges and performance I've no doubt many people have used Western's data for post 2004 Lovex loads though. Western was nevertheless making the point that they're not the same and having failed to stop over-stickering covered itself legally through the warning. This has nothing to do with new owner Hodgdon directly. Somebody has simply gone through the former Western Powders' website and reloading data documents and altered company names where appropriate to reflect the new ownership.
I don't know if such over-stickering continues. My recent purchases are 100% 'Lovex'. Explosia a.s. continues though to show 'similar to' links to today's Accurate grades in its Lovex material and equivalent pairs are shown side by side in burn rate charts. In the USA, Explosia powders are now being again imported after a 15 years absence by Shooters World which uses its own names for the Lovex grades it has adopted, but usually with a Lovex link too. It is building up its own database of pressure-tested loads including some of the many US originating cartridges that Explosia ignores (eg 260 Rem and the Creedmoors), so its website can be worth a visit for some Lovex powders. It seems though that D073.5 hasn't been adopted by SW.
