SF offline player not syncing!

Hi all, I have a Call of Cthulhu campaign with different soundsets. They are visible on the web player. However, they are not in visible in the MacOS SF offline player so I can download. I am signed in. I have rebooted numerous times. I have included a screenshot showing parts of the interface of both web and MacOS player. I have a session later today. Can anyone please help? BTW: all these soundsets ARE visible in the iOS offline player on my iPhone. However, for other reasons, I cannot use my phone for my session tonight. Help!

I think I have the same problem.
In the web player on the PC I can see all my soundsets (they were also created there), in the app on the Android tablet I can only see one of my soundsets. Overall, the list also looks very different.
