Bug? Can't increase Engine Scalability Settings

I have a project that I’ve been working on since 4.9 (now in 4.10) that I am unable to increase the engine scalability settings for. I can turn them down, but not up. If I go to Settings → Engine Scalability Settings, and increase some of the settings there, they don’t seem to affect my game level at all. If I then close the menu and re-open it, the settings are back to what they used to be. I have attached an image showing what’s going on.

Is this a bug? Is there some master list of settings that are overriding these? This project was partially worked on by another person, so I don’t know everything they did.

Is this a known bug or no?

This question is now 5 weeks old, is this a known bug or not?

Try uncheck the option for Monitor Editor Performance in this window

Had the same problem, I copied my post processing details over to a new volume then deleted the old. Seemed to sort itself out after that. Effects is still not going to epic still though. Will update you if I fix that section.

Even if I uncheck that I see the same behavior.

This did not fix my problem either.
