Studio version 2020.10.2 the ST-NMG-004 rule keeps saying display names are duplicated when they aren’t. Display names I’ve only used once, it says I’ve used them twice.
@postwick we had a bug in that version of Studio for this specific rule. I recommend updating to the latest patch for 2020.10 to have that fixed. Otherwise, you can try the new 2021.4 version that brings new features and improvements.
