macOS 15.2, InDesign 20.0.1

Problem: Metadata inside an image not being recognized by InDesign 2025.

Details:

Multiple images from different sources containing metadata that InDesign doesn't recognize
Presence of metadata in XMP Description field verified in Bridge and via InDesign's Links panel XMP File Info command.
Generating a Live Caption or Static Caption when using the Description field returns "<No data from link>".
Setting Object Export Options > Alt Text Source to From XMP: Description results in "metadata property is not present on some selected content".
When a PDF is generated using the images in question, the metadata is not passed through to the PDF, resulting in missing alt text accessibility errors.
Manually writing (or copying and pasting) the metadata to the Alt Text Source as Custom works, but as does manually creating a caption, but automation is the point.
