SLAB DOES NOT SHOW IN SECTION

[EXPODTL]

Archicad 20

THE SLAB WILL NOT SH0W IN SECTION BUT IF YOU CLICK ON WHERE IT IS SUPPOSED TO BE IT LIGHTS UP AND SHOWS THAT IT IS THERE. 

1. I TRIED ERASING IT TO MAKE SURE THERE WAS NOT TWO WITH EACH ONE HIDING THE OTHER. 
2. ALSO, I MADE SURE THAT IT WAS NOT SHOWN AT THE WRONG HEIGHT. 
3. TRIED COPY AND INJECT OBJECT TRAITS BUT THAT ALSO WOULD NOT WORK.
4. I ALSO TRIED COMPARISON OF SLAB COMMANDS, CHANGING COMMANDS TO MATCH SLAB THAT SHOWED CORRECTLY.  THAT ALSO DID NOT WORK.  SHOWN HERE IN RED ARE THE COMMANDS THAT I FOUND THAT WERE DIFFERENT AND CHANGED TO TRY TO CORRECT.
5. I ALSO CHECKED TO SEE IF SLAB WAS LISTED AS EXISTING AND IT IS LISTED AS NEW CONSTRUCTION.
6. PLEASE TRY TO REVIEW AND GIVE ME IDEAS ON WHAT I AM DOING WRONG?

Ones that were changed to match one that works.

It still did not show up in section and it is marked as new work.

Could it be that there is more than 2 slabs - so deleting one still leaves more than 2 behind?

Try a new section and maybe even one looking in a different direction.

Have you checked to see if the slab is intersecting with a wall/roof or slab that is hidden but on the same layer number? I had a similar problem where I had used slabs to do the bulk and massing for a project, put these on a hidden layer but when doing sections they were still stopping the final floor slabs from showing up. By the time I'd gotten to this point I had forgotten I had the bulk and massing as a layer at all. Try opening in 3d with all of the layers turned on and see if there could be any clashes with much larger objects.

Try a different building material for the slab and check the current material settings?

Yea, usually that is the case when 2 slabs are overlapping with each other.
