That KUID is the PaintShed 54ft_covered_hopper that is not in TC.
There are ways to fix it.
You could try the ja file thing to bring over all TRS2006 content into TC.
Or just Open KUID:-10:199 for Edit in TRS2006 CMP.
Close TRS2006 CMP.
Open TC CMP.
Import Content from the TRS2006 editing folder.
Close TC CMP.
Open TRS2006 CMP and Ctrl-R KUID:-10:199.
