Random Guid group names in Bundle Layout Preview analyze rule

I'm failing to understand why some of my Addressable group names are just Guids when I run the Bundle Layout Preview analyze rule.

I'm trying to debug why the lightmap for MainScene is not loading correctly and I noticed that while MainScene scene is explicitly added to the Remote group, the lightmap does not appear in the Implicit section of remote_scenes_all.bundle but instead is in the b579e...._scenes_all.bundle.

I checked the buildlayout.txt log and can't find any mention of these guids. Why are some groups reported with these incorrect names?
