This is just how MSFS works, the liveries 'overwrite' certain files and if you change the files on the base version the livery can break it.

VNAV - I've only done one flight so far and had a lot of issues with vertical profile on descent. It decided to ignore every single altitude constraint, would randomly start showing a massive climb then descent between waypoints, and once drew a flat line past the next waypoint, then back down and left, making a Z shape. I tried changing altitude constraints manually in the FMS but it wouldn't let me enter anything in the text boxes at all. For liveries, you should expect them to not work or for pink stuff to appear until the livery itself is updated.

Can confirm zCore HUES was the problem, removed it and it's working now.

Same problem. Fully uninstalled, cleared WASM, removed all liveries, reinstalled, still happening.
