Membership, strange commas in the Subscrition level column oon the all members page.

Hello,
I was changing the membership system from a dripped content over 12 level back to a normal one level membership. I have a visitor level and then a members level. I have deleted all of the 12 previous levels, and added them all to the members level.

Now for some strange reasons there are comma's to mark where the old levels where in the Membership level column.

I am concerned that is could be causing other strange behavior, if it is still treating these as ghost levels.

Any help on how to get rid of these comma's and ghost levels or whatever they are?
