can not remove managed private endpoint

Hi,

I created an Integration Runtime Virtual Network. Then I created a managed private endpoint with a blob storage. I approved the request on the Storage Account, so the connection was setup. Then I removed the endpoint on the Storage Acount side. And now I have a problem...

In my Data Factory the private endpoint was immediately published on creation (I created it in my feature branche). So the Endpoint is still in the Live Data Factory. If I want to create a new endpoint, I can not. 

The following message is displayed: "Failed to save <endpoint name>. Error: Invalid resource request. Resource type: 'ManagedPrivateEndpoint', Resource name: '<endpoint name>' 'Error: A managed private endpoint to the data source already exist.'. Please switch to live mode and check whether there is an existing managed private endpoint to the data source."

The private endpoint is still there, but i can not access it, neither delete it. 

Does anyone know how I can delete the endpoint in the publish-branche?? Merging a new change won't work. The endpoint is still there...

Thanks in advance!!
