Files matching a conditional filename save filename as metadata

[Roshri]

Bug description

I just recently found out Grabber can embed metadata to files so I added these conditions

but whenever I download a file that matches a conditional filename, instead of any of those fields, I get the filename as metadata for all the XMP fields

Steps to reproduce

1. Have a conditional metadata set, in my case I have one for the tag "Official Art" %copyright%\%date:format=yyyy.MM.dd%_%character%_%artist%_%md5%.%ext%
2. Save metadata with exiftool 13.22
3. Have files to be converted to webp
4. See error

Expected behavior

Metadata should be filled with correct tags instead of filename

System information

• OS: W10
• Grabber version: 7.13.0
