Unsaved options: Bug or failure on my part?

So in order to play Black Mesa I have to change options such as difficulty, model quality, etc… One annoying thing is that once I close the game, when I reopen it the changed options are reverted. Is this a bug or am I not pressing a certain button or changing a certain option? Thanks

It is a known bug.

Thank-you. That’s actually it for anything that has been going wrong with my game, so thank you everyone for your help!
