Error when making weather file with Elements

I am trying to make a weather file based on measured data from 2024, from other posts I followed the advice to use Elements to build it. I followed the steps to make it and it seems the file should work fine, but when I load it into DesignBuilder I get several errors and when I try to start the simulation I get the following error:

"Building 1 - Error reading header in weather file: C:\ProgramData\DesignBuilder\Weather Data\2024Weatherfile.epw.

Please choose a different weather file or change FCFactorMethod ground temperature source to option 2-Model data on Location tab at site level."

I am unable to find this tab, what comes closest is the ground modeling options on Location level which has 4 options, the second of which is 2-Kiva basic. None of these 4 settings have an impact on this error. Could it be that my computer works with different seperators for comma and period than the standard US setting for E+? What other options can I look at to make my weatherfile for 2024 so I can verify yearly measured data?
