The error in red is displayed

When I try to import it into a map, an error message in red appears.
It seems that Present is gone.
in RustEdit , I'll note that if I change Present to a different prefab, such as Present_1 (I forgot the name), there's no problem.

I've loaded up in rustedit and ingame and Its all fine and working for me, are you on the correct version of rustedit and rust?

Changed Status from Pending to Work in Progress

As a test, I created a new map and placed only this one prefab, but I got the error shown in screenshot.
I suspect this is probably because I'm disassembling grouped items, which is why the Present setting I wrote is affecting it.
I've checked with the latest RUST server, client, and RustEdit.
The reason I disassembled it is because the parts I mentioned in a previous discussion (https://codefling.com/prefabs/terrys-thunder-raceway-christmas-3?tab=comments) remain the same, so I disassembled it in order to make individual corrections.
