Software restriction policy - network map path rule not working

HI,

My additional rule allowing a network directory \\myserver\directory is well allowed

But another additional rule to the same location through a network map ( P:\directory ) is not.

The default software restriction (disallowed) still applies.

I've checked its presence into HKEY_USERS\{UID}\Software\Policies\Microsoft\Windows\Safer\CodeIdentifier\262144\Paths\{ID}
