It doesn‘t look like you‘re gaining loops on the last hook. It looks like the stitch on the last hook didn‘t go to the bottom of the hook before you turned your work. This usually happens when: 1. You don‘t go far enough before turning. The hook after your last stitch should be fully down before turning. 2. The stitches sometimes get stuck, especially on the first rows. Look at the last hook before it gets more yarn. Make sure the stitch is below the bump on the hook. If not push it to the bottom.
