YES! And this is something I wish they'd change in BFD2.
Here's the fix... if it helps, you owe me a Morgan-N-Coke! We'll drink one together.
When you save the kit, you also have to save the Keymap. After both have been saved (and the mixer, if you made any changes), save the whole shebang as a PRESET.
Here's the tricky part:
When you load the preset, unless you click the box on "Load Keymap" it will NOT load the map! WHAT?!?!?! I have no idea why they had it default to NOT loading the map with the preset, but I wish they'd change that. So, click Load Preset, and then in the chooser window, be sure to click "Load Keymap" at the bottom.
