First image is scrolled past the primary group.
Second image is further down from the first image revealing a duplication glitch.
These images show that when you scroll down on the mobile groups tab they are duplicated / replicated multiple times before going on to other groups, which then happen to be duplicated as well. This happens every time and it’s not a major issue but still quite inconvenient to have to scroll a lot, anyway the screenshots should be enough proof and apologies for no tags as I posted this on mobile.
