Unable to restrict Stores by responsibility when the stores shares one content zone or more than one

Hi

We have an issue in iProcurement, we are in 12.1.3

When two stores fixed to two distinct responsibilities shares one common content zones, both responsibilities show both stores.

The expected behavior is that each store could be only visible from the responsibility that was assigned to.

In the test cases, happens the following:

Responsibility X ==>Content Zone A, Content Zone C

Responsibility Y ==> Content Zone C, Content Zone D

Store X ==> Content Zone A, Content Zone C

Store Y ==> Content Zone C, Content Zone D

Content Zone C contains item categories that should be visible by all stores, instead of this, content zones A and D should be visible only by certain group of users grouped in the responsibilities X and Y.
