How to remove languages from SAP CAI bot

Hi, I still have the problem that the bot is interpreting asked questions sometimes as asked in a different language than English (even if all questions are entered in pure English). So it interprets it as French, Italian, Catalan etc.

Obviously there is no way to make that thing understand the proper language. However, I learned that removing all languages but English should solve that problem.

Question is: HOW can I remove all other not needed languages? If I remove - let's say in the French tab - an item, it disappears also in all other tabs (including the English tab where I NEED the item). So, again HOW can I remove all not needed languages?

Thanks,

Frank
