I understand. Unfortunately, I'm not able to "fix" this. This is inherent in the game itself and it simply doesn't fit in there because there are so many qualities.
If there are a lot of qualities, either ignore it or set 10Q mode :)
This is just part of the game. It only does this when you put quality modules in the building, right?
I don't think it can be removed, it's part of the description of the building with the quality. If it can be removed, I don't know how :( I can try asking the community
In the second image, I added a quality module. (You can see that it has +2.5% quality.)
This is in purely vanilla factorio, and no bullet point list is displayed.
A little thing that might help here is that in the settings you can edit where that display shows up in Settings -> Interface -> Tooltips -> uncheck Entity tooltip on the side. It might take some time to get used to, but it should stop the overflow.
