Well it looks like there is an actual hole in the leather. But it’s a bit smaller than the other holes. So it didn’t pull the thread through the leather. We’ve been messing with the stitch length and it seems like the longer the stitch the worse it gets for whatever reason. But now that we replaced the needle maybe the length could be adjusted which might now be the new issue. Here is a pic of the hole... with the bridge still in tact.
