Transcoding from user profile broken since DLNA is a plugin

[SamHawkens]

dlna user transcoding profiles are not working for me now that dlna is a plugin.

I copied my previously working profiles from
/etc/jellyfin/dlna/user/
to
/var/lib/jellyfin/plugins/configurations/dlna/user/

server is version 10.10.3 (native installation, not docker)

The log shows

[ERR] Error parsing profile file: "/var/lib/jellyfin/plugins/configurations/dlna/user/iTuner 320 ME.xml"
System.InvalidOperationException: There is an error in XML document (42, 85).
---> System.InvalidOperationException: Instance validation error: '' is not a valid value for MediaStreamProtocol.

So at least jellyfin reads the profile from the new path. Any hint what's wrong here? It used to work before dlna became a plugin.
