NLP 3.0.2 does not export ISO and Date to EXIF

Hi all! Longtime user, first time poster

I am failing to get NLP to export the NLP metadata fields of “ISO” and “Date” to standard EXIF tags. Either I’m missing something subtle or I’m hitting a bug.

Here is a screenshot of the metadata fields of an image in lightroom:

I’ve tried several of the default export settings, here is the For Flickr one where I’m making sure “Write EXIF fields with Custom Metadata” is checked:

and confirming that metadata is included in the export settings:

Yet when I do this export, the ISO is the ISO of my digital camera on scanning, and the date is the date of the scan. From Preview’s inspector:

to add to the mystery, some fields are correctly exported. The Camera field from NLP is correctly overwriting the TIFF tags, showing my Canon EOS-1n film camera rather than the Sony digital camera I use in the scan:

Indeed, if I import this photo into the Photos app, you can see that the film camera metadata is exported, but the ISO and date is not:

What is going wrong?

The mystery deepens. When I inspect the exif tags using the “MetaImage” app, it looks right, but in Preview’s inspector, it does not? what?

OK, i’ve made some progress.

It appears that there’s a conflict between the raw camera tags and the NLP export tags.
If I put the export “Metadata” field to “All except camera & camera raw”, then the ISO is correctly written from NLP to the exported file:

The date and time is still the captured time though.

I’m also having the problem where my date is not being exported to exif. I’m not sure if it is due to my system date format being not the default (mine is yyyy-mm-dd).

Have you had any success in these past months?
