Do you have an update log for all the stuff changed in Waterdeep? I cant tell any differences. It is mostly my lack of perception skill or my roll is bad, but it looks the same to me.
The red flag indicates a change in any part of the soundset. It could be as simple as changing a reverb setting in an element or as complex as adding a mood.
Usually it’s just maintenance work, evening out some bumps, so most of the time there isn’t really a need for a change log. Note that it will also effect any soundset the worked on thing is in, so you probably have more than one flag. 
If there is something major changing, having a change log would be a good idea though.
There were a few small changes.
- I added an ID voice on the “Official D&D” OneShot"
- In Yawning Portal, I made significant fixes to Durnan’s voice
- Other stuff I can’t remember.
