If this helps, as far as I can tell from having experienced this bug myself, this applies to every guild lab level and to every team that includes a card with a leader skill that affects the HP in any way, as a leader or as a helper. I think the problem is related to the fact that the guild lab HP bonus isn't accounted for during any recalculation of the maximum HP (which is necessary following a game freeze and reload or after the seal effect on the hp boosting card).
For this reason I believe that having information about his guild lab level or his exact team won't be much of a help, but this is only what I believe.
EDIT: I just tested and I can also add that this bug does not apply to the attack stat during a recalculation, but only to the HP. The attack guild lab bonus was kept. I would guess recovery is unaffected by this bug as well.
