All filters tested, with and without Dev mode on. Version 1.23.12.0
All working fine.
However, not on steam. Store version tested on pc.
Did you install updates from Content manager?
Did you restart MSFS after SU8 and again after Content Manager updates?
Rebooting pc is always a good idea too, after any install, update or uninstalls(for any program, app, etc) as this clears the ram and some temp files.
Did you install the Beta test SU8 and did you leave it per instructions [Beta] ?(https://forums.flightsimulator.com/t/instructions-for-beta-transition/501299)
