When a raw file is imported with the option Copy As DNG and a metadata preset is applied during import, the values set by the preset disappear from the metadata panel after a couple of seconds. A workaround is to set the option Catalog Settings > Automatically Write Changes Into XMP.

To reproduce on LR 14.4 / Mac OS 15.5 (see the attached screen recording):
1. Download and open this catalog:
https://www.dropbox.com/scl/fi/97ztsg16ekxc2h297lv4w/copy-dng-metadata.2025-06-23.zip?rlkey=9iqixpst...
2. Define a Metadata preset "Copy As DNG" with the fields:
Caption: Hello world
Copyright Status: Copyrighted.
Copyright: 2025 Joe Cool
The preset's .lrtemplate is in the catalog folder.
3. Verify Catalog Settings > Automatically Write Changes Into XMP is unchecked.
4. Do File > Import and import the file DSC00002.ARW from the catalog folder, with the options Copy As DNG and Apply During Import > Metadata: Copy As DNG.
5. Select the imported photo and observe that initially the Metadata panel shows Caption, Copyright Status, and Copyright as set by the metadata preset. But after a second or two they clear (incorrect).
6. Select the imported DNG and delete it from disk.
7. Set the option Catalog Settings > Automatically Write Changes Into XMP.
8. Repeat step 4 to import the raw again. Observe that this time, Caption, Copyright Status, and Copyright retain the values set by the metadata preset (correct).
