Comments are editable with "edit"-Button

Hallo again, i’ve updated your latest Version 6.1.2…all is perfect but i think there is a little issue:
when i write a comment and click on “send” , the comment is written and displayed, but in the “send”-Button is now written “edit”…so okay my comment is now editable, but it doesn’t change if i return after clicking next picture: so i can’t write a new comment execpt to edit my last!

PS: In my settings is active that i get a notice that my comment is successfull sended, but it doesn’t appear anymore…:(
