"Create Cluster..." only works when I have just one part

[[Ni...]]

Hello,

First time posting here, I hope I'm doing everything right.

I have a problem with cluster creation (Zeiss Inspect 2025.1.0.1985). Everything works fine when I have one part (picture 1). I can create and copy a cluster with no issues. As soon as I add another part (doesn't matter if it's empty or not) I can no longer create a cluster and I get this message (picture 2). I haven't found a workaround for this issue because no matter what I select I get the same "Please select nominal element" message. Is this a bug or am I doing something wrong?

I need to add another part because I want to inspect a digital assembly of two separate scans. I'm taking references from one scan to measure features on another scan. I need to use clusters because in total there are around 300 measurements. 

Any kind of help would me much appreciated!

Thanks!

Hello Nikola,
This is a bug that will be solved in the next software release (Service Pack 1)
For a solution for this particular case until the release, more details would be needed. At best contact support for this.
