Hi Thomas,
Have you used Pix4Dcapture for your mission? If yes, you should be able to use the *.p4d file that contains the correct geolocations.
Have you tried the workaround proposed by Blaž here?
If yes and it still not work, could you please upload your images either on the Cloud (and provide me the name of your project) or here (in a zip file):
One drive
So we can have a look a try to provide you the most adequate solution.
Best,
