Brush Settings not saving

Hello! I am having an issue with the brush settings. Every time I change something in the brush setting and then switch to another brush and back again, the setting resets to default. I have tried making brush presets too and those don't work either. If I lock a setting, it locks for all brushes. Does anyone know why this might be the case?  Sorry if this is a dumb question.
