convert entities not working in assembly- edit part

hi all,

I'm in an assembly - edit part, and trying to project the cutouts from one part onto another parallel part as a sketch. For some reason convert entities is not allowing me to select the edges of the cutouts as it usually does. when i try selecting the edges a message comes up saying " cannot use selection. Allowing this selection would create conflicting contexts".

Is there something in my settings in need to change to allow this?

if anyone has a fix for this please LMK.
