cat bones visible in actor animation

[aliaszz]

hi i have seen an other post/thread.
on cat bones visible in actor animation

and that you can simply disable the display operator and the bones will not be visible.

that works for cat files with one animation.
yet cat files with like say another world, local or absolute
animation layer added. 

so 2 layers of animation. one walk cycle, and one correction layer or added animation
then disabling the display operator doesnt work.
and the bones are still visible in viewport and rendering

please a solution.
