First rod in MembersTable: storage after creation

Hello,

with API II, I noticed the following bug when creating the MembersTable:

The first member in the table is always assigned a support upon creation, even if this attribute is False.

This behavior occurs exclusively during creation (.create), not during updating (.update).

Of course, I have attached an exemplary model and script to reproduce the issue.

Best regards

Hello Benedikt,
I was able to reproduce the problem and have forwarded it to the development department.
