The following UseCase leads to "unpublished" (=yellow) Assets in the assts app:

• Create a folder
• Upload 2 assets to this Folder: Asset-A and Asset-B
• Publish the Folder using "Publish incl. subnodes"
• Edit Asset-A and immediatly publish the asset directly
• Edit Asset-A again, it becomes yellow
• Edit Asset-B, it becomes yellow
• Publish the Folder using "Publish incl. subnodes"
• Asset-A is not published and stays yellow (forever!)
• Asset-B becomes green

• This UseCase can be tested on demoauthor
• Some more Details are described in SUPPORT-10581.
• The Problem Comes from the configuration of the Actions, the "Publish" Action uses the Version catalog, while the PublishInclSubnodes is using the Default catalog.
