Using the text to columns option on a comma separated file in csv format leads to the right preview in the text to columns wizard.
The column titled "ATTIC: Zone ..." shows the desired format in the preview window. Please look at the screenshot 1.jpg.

After pushing the finish button to obtain the result the number format gets suddenly changed and differs from the preview.
Again check for the "ATTIC: Zone ..." column as reference: 2.jpg

Is there a menu where one can look up, or specify how to format data to force the right comma placement? What settings might be wrong?
Thank you for any hint!
