I have something that somewhat randomly keeps happening, which is my random between two curves parameters don’t allow me to create keyframes pertinent to the second curve (it just turns it all into a single curve?)
Never had this issue. I’d recommend restarting your windows layout or deleting library to get a totally clean UI cache. Maybe a different unity version could help too?
Library is the unity folder where it keeps all the cache.
Close down Unity and delete this folder: YourUnityProjectFolder\Library\UIElements
Then after you re-launch Unity it will regenerate all UI related cache. Might help, might not help. I had some issues with UI after Unity transitioned to UI Elements and deleting the folder did fix some problems.
