WACUP seems to not correctly display the metadata in my WMA files where Winamp 5.8 displays it correctly.
Because of that the Last.fm Scrobbler plugin (ml_wa2_scrobbler) does not get the right metadata.
The metadata in WACUP is missing everything but "Title", "Artist" and "Album Artist" and it's missing the last character in these.
I have attached a screenshot with the "Edit Item Metadata" window of both WACUP + Winamp 5.8 and mp3tag.
Maybe useful information:
WACUP Version: 1.0.13.5864 (Jul 23 2020)
Audio File Format: Windows Media Audio 9.2
