Running Average line thickness differences when using Groups

Apologies if this has already been posted, but I was unable to find anything because I’m not really sure how to describe the problem in proper terms (newish to wandb).

I use Running Average for my line plots and have “Group runs by…” set to Groups to compare various runs. Here’s an example of what I expect to see:

However, what I’ve found in the last few weeks is that the graphs end up looking like this:

(I had to disable “Use grouping from the runs table in charts” in order to give an example so please ignore the legend differences. I can’t use this as a workaround as disabling this option defeats the purpose of grouping for me.)

This behavior started a couple of months ago and at the time, I was able to add a second “Group runs by…” option (User) and things looked good again.

As of today, however, even the extra group option gives me the same results where the line thicknesses of the min/max are the same as the average:

I’ve reviewed my settings many times since this started and I’ve not changed anything to trigger this.

Here’s a zoomed-in example of just a single run to better illustrate the difference:

Any suggestions would be appreciated!
