Computer Help and Support

Maybe it's because you don't have a lot of contacts/groups and FB does need to fill up your page so you get repeats. I know that some small groups I belong to show older posts at the top, even though no new replies are there, and then new ones are farther down the page. It's not supposed to work that way, but it does.

Another issue could be how you scroll down. If I use the slidey arrow on the side I am always getting jumped back up to the top of the list. I don't have that problem if I use the down arrow on my keyboard.

Hope this helps.
