Unable to access parameters on some models

As you can see, on some older models, i cannot access the parameters through FE2.
Can you tell me why this is the case?

Selection Info is being actively worked on.

As ever if the web team could share the impacted stream as a test case it helps a lot.

Hey Dick! As Jonathon says we’re actively working on this right now. Can you send us this model (in this thread or in private) so we can check why these specific parameters are inaccessible?

Hey, I will slide it into the DM
