NOTE: My company recently upgraded from SW 2022 to 2024 SP 5.0

I have a hinge assembly (for proprietary reasons, I cannot post screenshots). In this assembly, I have two configs, DEFAULT and FLEX. FLEX is a derived configuration of DEFAULT. There are two mates I need to suppress for FLEX to work properly. However, when I suppress them in FLEX, they also suppress in DEFAULT, and when I unsuppress them in DEFAULT, they unsuppress in FLEX. I have never had an issue suppressing/unsuppressing mates in derived configurations. Is this a bug or did something change between SW 2022 and 2024?

EDIT:

To clarify, the two mates are NOT supposed to be suppressed in the DEFAULT configuration.
