Promoted threads on my Home page, but not on my All page

Already purged all caches and updated, still seeing this problem:

I'm seeing various advertisements on my reddit Home page, but not on the All page, multireddits, or my Saved page. They're made to look like normal reddit threads, but with a blue bullhorn icon on their left and "promoted" in blue with the same icon where the comment button would be on a normal thread.

Is anybody else seeing these ads? Any idea on how to make them go away? I'm worried if I zap them then it could lead to me missing out on legit content.
