Looks like there is a little problem with the DMS location format analysis :
In the example above, 31°24'12.2"N 12°10'26.5"E goes actually to 31°24'12.2"N 2°10'26.5"E.
Only the units (last digit) of E coordinates is taken into account.
For the North coordinates, it's OK.
With the DDM model, it's also OK
