Hi,
In that case, I can instruct you how you can remove empty blank spaces from the answers. To do this, open each and every question from the admin panel. Go to answer fields and keep the cursor at the end of the answer. Hit DELETE key to remove any empty blank space at the end of the answer. Also, look for the blank space at the front of the answers.
If this does not resolve the problem, please roll back the QSM version to 6.3.5.
Kind Regards,
Kriti
