On Available Devices/Plugins, Delete shifts up the list of devices but fails to shift up the Show ticks, thereby leaving the ticks placed on the wrong devices.
[EDIT:]Further info: that report was for non-skinned, but skinned is the same.
Here it is (on skinned):
1 Insert 'CJJ stick', pause, withdraw.
2 Call up Options Portable/Audio Devices and see:

3 Click CJJ stick then Delete
4 See

Doing OK and calling up Options Portable/Audio Devices again shows the messup persists.
