Coursepress Pro deleting answers

Hi,

Course press pro works fine except when a student types in an answer to a question and saves it and moves on but when they go back to any of their previously answered questions and then start to type to correct it it wipes the entire answer. The user/student cannot amend a previously entered answer without wiping out their existing work. Is this how the system is supposed to work or is there a setting issue or a separate issue at play here.

Regards,

Simon
