This sounds expected. The question is why would you have any constraints to
use the same channel on the P2P interface as the one used by wlan0 interface
on a different radio? It would even be beneficial to use a different channel in
such a case to avoid interference between the interfaces.

As I wrote earlier this won't work ok in all cases.
