Had the same issue on newer versions of bluez-utils. Downgrading it to 5.6x fixed my issues.

Pretty sure there is a setting for it.

That’s because you get an error a lot of times if you use proton-ge or wine-ge in lutris or bottles when installing. The trick is to use system wine for installing and then switching to wine-ge when the install is done.

IMO, just ignore the grading system and have fun. Once you’re hooked enough and actually want to improve, that’s when you will want to start paying attention to it.
