Jo, if a client that pushes to GitHub without doing a refetch+PUSH to nostr or if youre using a push with a GRASP server list without gittr explicitely in we'll be behind until we see the event. The bridge than has an old state until it sees the new event and syncs up and showed so.
Like here the last commit on GRASP was a different than (lastest) on GitHub. Bridge will fallback to newest incl. external source in gittr, in your pic that got lost but seems fine now to me
