Grey flat panels ruining my day

[Digup]

Hi Everyone,especially experts.
I have grey panels that seem to be be some kind of alighnment panels or flat wall-like markers. How do I get rid of the, turn them off, or learn to use them accurately. Please help, I'm spending way too much time trying to figure this out.
Thanks to all who reply....

This could be some room ceilings which are not correctly computed.
Display the modification dialog box of each room where it happens and select the Flat ceiling only check box or make the ceiling invisible if needed.
If this is not the problem, you’ll have to share an image so we can better understand your issue.

To clarify, the wall-like gray panels are thin verticle planes, not flat horizontal like a floor or ceiling.
Puybaret, thank you much. I will try your suggestion, but it seems more like an alignment issue. Can I shut this tool off?

It is not clear to me whether it is some object of yours that has some purpose when creating the plan, or whether it appears when drawing the plan. Mostly when drawing walls, it would be preferable to have the Magnetic option turned on, and if it is necessary to adjust an angle inside the room, turn off the Magnetic option and adjust the angle manually. In this way, all walls are properly connected and unwanted artifacts cannot appear.
