I have seen this one other time. I think it has to do with how things get reset during the New Year Setup. Here are a couple of things to try to take care of this:
1. I suspect the LIT checkbox was already checked when you assigned the club. Uncheck the LIT box, then save the record, then check it and assign the club. That should work. If not,
2. On the Main tab of the Member Form, open the Roles Dialog (put your cursor in the empty space below or next to the fields and right click to get the pop-up menu options). There should be two roles. One is the clubber role and the other the LIT role. If there are extras, delete those. Once you have one LIT role, be sure the club name is correct there.
If those suggestions don't take care of it, please contact support and we will schedule a remote support session to look at it.
