Maybe not a bug, but just something I am not a fan of.
Once I watch an episode, it does not get set to blue (viewed) when it returns to the episode selector.
It will only mark it as viewed once you exit one screen, and go back in.
I tested this by watching multiple episodes (fast forward to "end") and as stated, will not be marked as viewed until I go back one screen and return.
in case it matters, my filters are
Series -> by series -> by season -> large view
