We moved some issues from a new gen project to an older gen project but some cards in the sprint show the old reference (from the New gen project HSS_130) at the top of the card. The reference for this story was HSU-22 and the epic is from the correct project. When you click onto the story you cannot see the HSS-130 issue.
We can see the story in the sprint but when you look in the backlog the issue does not show at all.
