ISE ERS 2.6: Bulk Requests Endpoint IDs

[Logorrhoe]

Hello Community,

I am currently digging myself into Cisco ISE ERS and I am facing one or two issues which I can not explain myself.

Basically I want to add Endpoints to a group. Single Requests and Bulk Requests work like a charm. 

I am facing strange behavior with Endpoints created by Bulk Requests when I want to delete one of this endpoints.

Bulk Request for adding:

<?xml version="1.0" ?>
<ns4:endpointBulkRequest operationType="create" resourceMediaType="vnd.com.cisco.ise.identity.endpoint.1.0+xml" xmlns:ns4="identity.ers.ise.cisco.com" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
        <ns4:resourcesList>
                <ns4:endpoint>
                        <groupId>ae0502f0-0c5c-11ea-900a-9aa53e3f4864</groupId>
                        <mac>CC:CC:CC:CC:CC:CC</mac>
                        <portalUser></portalUser>
                        <staticGroupAssignment>true</staticGroupAssignment>
                        <staticProfileAssignment>false</staticProfileAssignment>
                </ns4:endpoint>
                <ns4:endpoint>
                        <groupId>ae0502f0-0c5c-11ea-900a-9aa53e3f4864</groupId>
                        <mac>DD:DD:DD:DD:DD:DD</mac>
                        <portalUser></portalUser>
                        <staticGroupAssignment>true</staticGroupAssignment>
                        <staticProfileAssignment>false</staticProfileAssignment>
                </ns4:endpoint>
        </ns4:resourcesList>
</ns4:endpointBulkRequest>

When I list the group I will receive this:

{'id': '7f3f0fd0-432d-11ea-bf83-761ad25a0c69', 'name': 'CC:CC:CC:CC:CC:CC', 'link': {'rel': 'self', 'href': 'https://<ise-ip>:9060/ers/config/endpoint/7f3f0fd0-432d-11ea-bf83-761ad25a0c69', 'type': 'application/json'}}
{'id': '7f3f0fd1-432d-11ea-bf83-761ad25a0c69', 'name': 'DD:DD:DD:DD:DD:DD', 'link': {'rel': 'self', 'href': 'https://<ise-ip>:9060/ers/config/endpoint/7f3f0fd1-432d-11ea-bf83-761ad25a0c69', 'type': 'application/json'}}

Both of the Endpoints share the same ID.

Now I want to remove one of these MACs from the group and as a result both will be removed. 

Did anyone ran into the same issue or did it just worked "as requested"?

Thank you :)

Unexpected twist: I should see a eye doctor. ERS works just fine and the IDs do not match..
