I've noticed recently, that not all of the videos, that people I subscribe to, show up in my feed; even though I have checked "Only uploads".

I know other of TotalHalibut's (Totalbiscuit, The Cynical Brit) subscribers also has this problem:

Has anyone noticed this? Is it common? If so, how can I fix it?

Thank you,
