USR369 report: left the app and came back in. Current exercise was missing information but kept some. Went to History - also missing info, but different info missing than what was missing/kept in Current (i.e. the two views diverged from each other and from what was originally entered). USR369 wants persistence to be solid: whether leaving by accident or on purpose, or the app shutting down, both Current and History should stay exactly as they were, unchanged.
