You would have to find out how they get set up this way.  IIUC,
`rmail-maybe-set-message-counters' does this near the beginning of
`rmail-show-message'.  Could you tell me what value it gets there and
what the value of `point-max' is, maybe the buffer was narrowed in some
strange way and the third value is simply `point-max' (note that the
buffer is widened immediately after that).

This just removes a marker that is no more needed in order to not slow
down further computations.  I think it's not related to your problem.
