Buddyboss platform typing comment/message problem

Hi,
I am using buddyboss platform with translatepress. When I switch to the translated language, there is a problem with writing comments and messages. The point is, when I start typing the first few letters it jumps before the text marker.

This problem does not arise when the original language is set.

Can you help with that?
Best regards
Paweł
