bug report: automatic group renaming

Hello ARM team,
yesterday came across some weared situation.
The scenario was as followed:


Important: The share name is the same on both servers, the server names differ only at the last letter.
Permissions are already set:

Now, if it is set to auto rename the permission groups as shown in the screenshot, ARM will try to rename the groups to, for example, FS_ServerB_share_name$_RW if I change a permission on on ServerA. I think ARM does not check the uid in the description field which is as far as I know a unique identifier to the permission group.
