SP0-Connector triggers SiteCollection-Insert-Request twice (OIM8.1 - Sharepoint 2016)

Hi there,

I try to connect a Sharepoint 2016er farm with the OIM 8.1 System.

The Initialload is basically working, but during ad-hoc-provisioning i run into issues. When i provision a site collection i can see that the systemconnector tries to insert it twice. The first try is already successful but it seems that a ID (exception: Parameter Source NULL) of the site is not triggered back. The second try logically runs into an exception because of a unique constraint.

Does anyone ever had an issue like this?

2nd) Does anyone has successfully loaded non default and non #0 templates into the OIM-Database via the connector?

Thank you in advance!
