How to deactivate "Rating" and "Colour Label" in Categories filter?

[nji9]

Deactivating would be handy, as I do not need them at all.
As they take much place in my (crowded) categories filter pane,
and even more: both are always expanded even if I collapse them,
close and reopen XnViewMP.

Thanks for help!
