any reason why tagpaths are case sensitive in the gateway tag change scripts? They properly evaluate when using the “check tag paths” tool. I dont remember this being the case in version 7.6 and before. I also I dont recall any other area that case sensitivity is an issue with tags.

This is the error I see:
