Mask tool bar stays populated when fixtures are removed from patch

I just noticed today that the masking toolbar stay populated with kinds that don't exist in the patch anymore.

Repro

1. Patch show with movers and desk channels.

2. Create auto kinds

3. Notice when you record or merge the mask toolbar is populated with kinds that exist in the show

4. Remove movers from patch.

5. Call up Desk Channels, set value and start a merge or record. Notice that when masking toolbar pops up, that the old kinds from the movers populate the masking toolbar. The kinds are not selectable or greyed out, but they still exist making the toolbar bigger than it should be.

Shouldn't the masking toolbar omit any kinds that aren't available in the show like it would if you only patched desk channels initially?
