B-5 Settings Not Saving in Mainstage

[Clink]

I'm using B-5 2.2 in Mainstage 3.2.4 and was hoping to create a few aliases to provide instant recall of drawbar settings, etc. I can't get this to work properly. In a Mainstage concert that includes several songs, trying to save Set 1 and Set 2 user drawbar settings in B-5 is a big problem. It seems to save initially, but as soon as you starting switching from song to song, drawbar settings are lost and can almost be random at times. Any thoughts this issue? Thanks.
