Additional context
I tried it with/without creative and with/without OP

Sorry for so many bugs report, just wanted to let you know.

Thanks for detailed info. Fixed on latest dev build! (need test)

No problem :)
I tried to test it (quickly). It seems to be without any error, but I just tried to put chest inside the region and I was able to open it, but the claim was not mine and with "chest: false"
I made server region, check that chest is set to false and I am still able to open the chest.
I checked it also with LuckPerms and it was checking "redprotect.flag.bypass.allow-mod - undefined" when I was opening the chest. Strange :D

Tested here and all is ok... check for plugin load error on server starting or some other permission or op

Sorry, tested it again. Something was wrong in my config. With fresh new config - without any problem.
I will try to test it further and if I will find something, I will let you know.
Thank you very much :)
