Paintool added automatically when start simulaion

every time when I start simulation , the Paintool added automatically under my robot xforms .
I reallt do not know how to avoid it . It will come next time when starting simulation even though i delete it.

Isaac Sim version: 2022.2.1 ; 2022.2.0 ;
machine: 3070TI
workflow: individual workstation

I turn off all the extensions related “Paint tool” , It looks nice now .
But if i want to use the Paint tools, the problem will come back again

Can you try to disable the extension from the extension manager instead of deleting it?
