keke-bu Preston face bug

[N.Gamma]

I have a problem with the mod keke-bu Preston. Since on Nexus in the mod posts no help is to be expected, so I hope for it here all the more.
My problem is that Preston has no eyebrows (see picture). I actually only know this from the brown face bug. But since only Preston has the problem and no other NPC so far, it doesn't seem to be that.
I seem to remember when I last installed Fallout 4 a few months ago, that you have to delete some files from the LMCC, but I can't find the solution anymore. Can someone help me further?

Eyebrows missing is a known issue with True Brows (or some other mod that is in CBBE) and unfortunately, the solution without going into body slide is to revert to an older save.     Is going back one earlier save a workable solution for you?

The picture is from the first meeting with Preston, so that shouldn't be a problem. However, I have not installed True Brows. And as I said Preston is the only NPC that has this problem.

He's using vanilla assets so there shouldn't be an issue.

You "might" find that his brows are inside his head. Open him up in Looks Menu and play around a bit.

A-ha!  I knew there had to be a reason he's constantly sending me on more quests.  He has an internal Browser.  XD

Sorry, I was just making a terrible joke.  Don't mind me

Ok after I have now looked at Presten a little closer and his neck seems to have a different color, it is probably the brown face bug. but why has it only Preston and how do I fix it?
