Hello Roberto
This usually happens when internalizing/externalizing components within an assembly, the behavior is cyclic if an internal component is trying to be inside an external part, the external part will gain a component whose template lives in the main document, hence the cycle. I would suggest externalizing the component first.. Or check where the internalize operation is performed in the structural tree. Or perhaps it is not finding the file paths or has an incorrect path.
Let me still discuss this with the team, I will get back to you.
