There appears to be a bug in the import wizard where location name information is being lost and records being lumped together.

Easier to explain by doing:
- import the attached
- set the first column to location
- at the matching location stage, choose the same location for both 'meadow' and 'pit' (e.g. as two areas of the same site)

I would expect this to create two event/samples, one for the 'meadow' and one for the 'pit', but all records are imported into a single event/sample with 'meadow' as the location name.

If you add e.g. a grid reference column (with different grid references for each area) then the import works as expected.
