Some players may encounter some Language issues on Ultimate Evil Edition, which is because there are two kinds of language packs to meet different culture.  If you are experiencing this, now what you need to do is to follow the steps below which post by the Support Forum Agent:

Step 1: Remove the existing version of Diablo III: Reaper of Souls - Ultimate Evil Edition from your console system. The executable for the game is separate from the saved data, and if you’ve played Ultimate Evil Edition at all, you will only want to remove the game data, not the save file. To do this:

•On PlayStation 3
•Navigate to the GAME column in the PlayStation 3 menu > Game Data Utility > select Diablo III: Reaper of Souls – Ultimate Evil Edition > select OPTIONS > DELETE

•On PlayStation 4
•Navigate to SETTINGS in PlayStation 4 menu > System Storage Management > Applications > select Diablo III: Reaper of Souls – Ultimate Evil Edition > select OPTIONS > DELETE

Step 2: Once the Ultimate Evil Edition game data has been deleted from your system, navigate back into the PlayStation Store and look for it there (you will not have to repurchase the game, the record of your previous purchase is not lost). Select the game, and you will see that there are two different downloads available. The larger of the two is the English/French/Italian/German/Spanish (EFIGS) version, the smaller of the two is the Polish/Russian (POL/RUS) pack.

PS3
EFIGS 21.8 GB
POL/RUS 11.5 GB

PS4
EFIGS 37.8 GB
POL/RUS 20.5 GB

Step 3: Choose the appropriate download and the game will then reinstall. If you haven't deleted the saved game data (which is approximately 13 MB), then the new language version will pick right up where you left off.

Of course, you can easily buy Diablo 3 items and enjoy your game!
