Membership 2 Pro Profile Fields add-on "read only" option doesn't work on the account

Here are the steps to replicate my problem:

Create some additional user profile fields using BuddyPress. Then enable "Profile Fields" add-on in Membership 2 Pro. Set these fields as "read only" in "Profile form" column.
Now go to Membership 2 Pro /account page as a member and those fields will be editable for you, they'll also save.
