Same for me. Has been up a while and not been improved in the latest update.
Just now I created a nice sound using a purchased rig pack, stored it in the local library with the store button in the (Windows) Rig Manager and during this process - without touching any other button - I lost all the effects settings. They were still displayed, but were not used in the sound creation.
Sometimes when I click on another performance, the sound appears on this bank. Feels like the Rig Manager is always lagging behind one performance.
Maybe I'll use the store button on the Kemper more often...
