Can anyone see why this is happening? You can see from the screenshot below that I have used certain materials to distinguish elements in section. Once used, these normally show up in Colors in Model but what I see here is just the default set (not actually those I have used but are presumably automatically loaded). Is this working differently from SU 2018?
I just went back to working on the file and when I picked an existing material using the eyedropper, suddenly everything was back to normal.
I do seem to have some weird things happening. I have noticed that when I close a loop, quite often I get two surfaces created, one on top of the other. I canāt then apply materials until I realize and delete one of the surfaces.
Just me?
And hereās an example. I go to draw a line on an existing surface and double surfaces are created in the process. One of the new ones can be painted with a material but the other cannot. What is going on?
We can only guess unless you attach the model.
Iām guessing from that that it may indeed be peculiar to me or this drawing. Anyway, here it is then.

This looks like you have tiny inaccuracies caused by using length snapping.
I have changed the precision and you can see that things are every so slightly off axis.
Thanks @Box, it was driving me nuts. I canāt quite think how that happened. I produced some of the 2D stuff from a section slice. I guess I must have been a bit sloppy at some stage.
The created face that gets painted is dependant on: zoom level and graphic related issues like Antialiasing, pixels etcā¦
Not sure if there is a decapreation here.
Try this:
make a component or wrapped group, rotate a copy 360 and try to paint it:
it does not seem to be painted.
now, when moving is selected, the painted group is being moved, so there is some inconsistency.
Those tiny inaccuracies would not have an impact on the āIn modelā collection, though.
In the screenshot, there arenāt any patterns, at all, leading to suspect a Mac-related issueā¦
If you mean my screenshot? thatās because I went monochrome, I was more interested in finding why there were extra faces.
No, the very first post from @simoncbevans
It could be that there was some āCacheā in the Color Panel, and we can not say for sure, but in his second screenshot, they are thereā¦
I get the same result as you. I presume I was creating a new face because I was picking a slightly different location, even though it looked the same.
What is ādecapreationā? I looked it up but no dice.
I cannot reproduce the peculiarity again right now so perhaps it was just a one-off glitch.
I have made it up for you 
I think I meant decapitation, Features being cut of while upgradingā¦
There is no room for āone-offā glitches in software, I think, just circumstances changingā¦
The inaccuracies may be part of the problem, but there is a underlying glitch, as well.
Ah, youāve been coinifying new words, I seeā¦!
