Change of date made when trap 'condition' changed using walk the line

We have picked up that a number of traps have had the date they were checked on changed to 4 days prior when the trap ‘condition’ was changed.
See attached map, this is a ‘date last checked with map’ report. all traps shown were checked on the same day. Those traps showing 4 days since they were checked all had the trap ‘condition’ changed from ‘relured’ which was the default walk the line preset, to something else, this appears to have changed the date the traps were checked on to 4 days prior.
