Problem with Approval Phase

Summary:

Issue with Approval Phase

Content (required):

Hi All,

I have an issue related to Approval Phase.

I have an entity's node called "B_ALL". This is the official Hierarchy.

I created another entity node called "B_ALL_GBP" equal to "B_ALL" but with a different currency (in this case GBP).

I added this new node in the "Approval Phase" for mistake. Now I have to exclude this node from the "Approval Phase" but I have an issue (see attached image). For this reason I'm not able to complete the Approval Process for the Principal node ("B_ALL").

Could you help me?
