CATIA problem when creating functions from two splines

[r1xn]

Hi everyone,
I am facing a issue in CATIA when trying to create a function from two splines:

I have two existing splines and when i try to create a function e.g., using "Combine" the result is automatically named "curve" instead of the operator (see the attachment). The curve is non-editable, i cannot modify its parameters and I've also tried reinstalling CATIA. I'm currently running on CATIAV5-6R2024.
Has anyone encountered this and knows ho to fix it?

Thanks in advance for any tips!

Why would the result be editable?

The original curves should remain editable to alter the combination. The only parts of the result that should be editable are which curves are chosen to create it.

Other than that this is a Catia question and not an automotive question, so it's in the wrong forum group.
