When connecting multiple inputs to a variable in grasshopper, the name resets itself to the name of the module that is plugged into it. (see video to reproduce). I was using Ladybug Tools 1.80 with a 1.60 module that caused this behavior.
Sorry for delaying in reporting it due to time constraints. I just saw that 8.13 has been released, but am flagging this here in case it has not been addressed.
Can you reproduce this behavior with standard Grasshopper components? If not, this sounds like something that you need to report on https://discourse.ladybug.tools/
