I have a number of User Fields set up for my different membership levels, all of which are set to show at checkout and show on the user profile. I've noticed while testing that if I select a membership, fill out the user forms, and pay by Paypal, when I view the user's profile all of the user fields data is successfully saved. However, if I try using "Pay by Check" and fill out all the user fields, that data is not saved on the user profile and lost forever. I've tested this multiple times (select membership level, fill out user fields, select Pay by Check, submit form, set order to success, check user profile) and every time the user fields data will not save.
