Assassins creed unity ps4 english / german version?

A few days ago I got Assassins Creed Unity for the ps4, but the disc is the us version because I got it from my aunt in america. I was already playing happily and everything and wanted to get the updates, bought them for 8-9 euro and wanted to install them.

Playstation then told me I had to own the main game first, then called the playstation store and they said I had never owned the game and no trophies etc, although I have them, at least with the disc version.

she said then I should uninstall it and reinstall it, I did it, but then unfortunately had to… But buy the German version again for 30 euro in the sotre.

Now I have the following problem.

On the English version, I'm already at 12% progress, with good weapons and actually good armor.

after i started the german i have no progress whatsoever and have to start completely from forne.

does anyone have an idea how I can play it now? Since I only have the updates in German, but not in English.

can you sync that somehow? Without my progress being so completely over?

or

If not possible, there are 2 other games, synchronization is only possible for the same game.

And 12% is not really a lot, do a gamer night and you have everything xD again
