Typing in hiragana refreshes page

When I’m usuing my calssic review option it happens that if I put wrong answer (doesn’t matter if it’s in English or japanese hiragana) and after that I get another word which I have to put in japanese, despite I give good answer, it disappears and the word is refreshed waiting for answer. I have to put it few time (sometimes even 7) for course to let it through and accept it. This doesn’t happen if I use english alphabet, only hiragana.
This problem is not presented on mobile/tablet app but probably mainly cause I use those hint parts which are under. Problem is on Chrome browser with WinOS, but in LinuxOS with same browser everything is ok.
