Troubleshooting problem with file numbering display

[Budgie]

I know next to nothing about Vorbis comments. All I did in the past is use EasyTag believing I was tagging with ID3v2.4. More reading for me.

With regard to my "album" I only recently put the two file lists together in one directory. I am sure they had been ripped at the same but cannot be sure. It is quite possible however that some tag editing went on at different times, hence the different titles.

No idea about the disk number. Will have a look at what is showing on EasyTag again and many thanks for the help.
