I recommend finding scripts and right clicking and deleting the translations for it as RPG VX Ace games near universally have "special characters" in the scripts (like "\n" or "\[0]") which are replaced by variables when run, and machine translations (especially google Translate) love to change them and put spaces in them.
The scripts are usually only used for combat so it may be fine to just leave scripts untranslated, else you can go through manually and fix each error... So best of look

(they may also be used for saves but I haven't really looked into it)
Also a note about
"It depends which games you tried to translate, Translator++ does not work with all RPG VX Ace games."
That I'm pretty sure this is false unless the game maker has modded the RPG VX Ace engine to add encryption or like many plugins for RPG MV, have custom text that is stored elsewhere, The main issue is as above special characters. they are usually easy to see as they usually have [] around them or have a \ before them. All you really need to do about them is just leave them untranslated. Though sometimes this can be annoying as I found a game that used the names of Items to find the images of them so I had to leave them untranslated in the game
