Teams and Area permissions

In a Project I have 3 Teams. In each Teams I have one Area.

I want each member of a team to not be able to create User Story in other teams.

I have TEAM1 with AREA1

I have TEAM2 with AREA2

I have TEAM3 with AREA3

In Project Configuration :

For AREA1 I Deny access to TEAM2 and TEAM3

For AREA2 I Deny access to TEAM1 and TEAM3

For AREA3 I Deny access to TEAM1 and TEAM2

It works very well if a member is only in one Team.

But it don’t work if a member is in 2 Teams : in this case the member can’t access at any User Stoty

Can somebody help me ?
