Is anyone else having a problem with BIAB 2015 remembering favorites that they mark using the asterisk (*) in the RealDrum Picker dialog?

On page 245 of the manual, it says you can "click in this column to enter an asterisk indicating that this is a favorite" but sometimes (but not always) after I do this, then click OK, then return to the dialog box, the asterisk(s) that I have set up sometimes are gone, or move to other rows.

Is there a "commit" or "save" process that I'm missing?

Thanks in advance for your help.
