Microsoft Query error

Hello all,

I made a Microsoft Query in Excel to import some data from another workbook and now something strange happend.
In the attached file you can see the imported part on the left side and the original part on the right side.
As you can see, the second row on the imported part (left side) is 06.11.2017, but it should be 11.06.2017.
The rest are fine...

Any ideea please?
