IPTC Capture Date doesn't work properly or does it? C1 Pro 21 Mac

Hello, I import my files with Photo Mechanic. During this process I copy the capture date from the Exif data to the IPTC area.
When exporting the files with C1, I don't want to transfer Exif data, but all IPTC data. In earlier versions of C1 this was no problem. But now the capture date is missing in the IPTC data, instead the export date is entered as the capture date in the IPTC data. This is a very big problem for me. Am I doing something wrong or why was this changed in C1?
