Hello Toby,

After merging the files, certain columns are missing. These columns also cannot be selected manually, as they are missing from the selection options as well.
For example, I have a column "TgmName" that is missing in the merged files and also cannot be selected.
I would expect the structure of the columns in the merged files to be the same as in the individual files.

Single file:


Merged files:



Best regards,
Stefan
