Found the reason the files were m4a not flac
Converted to flac now all ok
Don't see why being m4a should be an issue for mp3tag
Thanks

mp4 tags have a strictly numeric TRACK field that does not allow the `/`
It would have been so nice to see the extended tags dialogue - as that probably shows the number of totals

m4a is used as a suffix for MPEG-4 Part 14 Audio containers. It can contain lossy encoded and also lossless encoded material. The metadata standard for a container has nothing to do whether an encoder works loss or lossless.

Usually the lossy variant contains AAC while the lossless variant contains ALAC.

If your files were not of the ALAC variant, you have transcoded from a lossy format (AAC in m4a) to a lossless format (flac), which wastes space and is a [bad practice](https://wiki.hydrogenaudio.org/index.php?title=Transcoding#Lossy-to-lossless_transcoding) in general.

See also the documentation about tag fields exclusive to mp4 files:

I am pretty sure that the extended tags dialogue now shows a field called TOTALTRACKS or TOTALDISCS with the number 22 in it.
Your column definition, though, does not reflect this split.
I would think that for value
`%track%[/%totaltracks%]`
would emulate such a display.

Pardon my ignorance, but isn't mp4 a video format, was referring to m4a ab apple codec
Thanks

You may have noticed the word

in the previous posts.
MP4 describes a container that may contain further data of different formats.
So m4a may be used for audio files, m4v for video files, m4b for audiobooks and mp4 in general. The tag format is mainly the same for all of them.
A screenshot of the extended tags dialogue would still be nice to give an example of the mp4-specific fields.

Bit the files say m4a not mp4 🤔

m4a is a subcategory of mp4.
What happens if you rename an m4a file to mp4?
Does it show a video all of a sudden?
Doesn't it play at all any more?
What would be the difference between mp4 and m4v?

The standard used is m4 **a** is audio, m4 **v** is video. Apple has extended this with other similar formats like m4 **r** for ringtones.

This is identified in the mp4 standard for tagging. They use distinct integer fields for Track, Totaltracks, Discnumber, and Totaldiscs. When it comes to sorting this makes it easier than dealing with a single field that includes the current and totals separated by a slash character.

It is not a problem for mp3tag. It clearly handles all parts of the standard for m4a quite easily and is documented in the support pages. I use lossless ALAC for all of my CD ripping as we have a mixed use household of Apple and Android devices. And mp3tag has been my go-to editor for a very long time.

It was already shared by @Casual_Tea why this is not a good idea.
I suggest you look at the original files in mp3tag if you still have them. If they are lossless ALAC and you prefer them to be FLAC, then this is not an issue. But if they are lossy, then I highly recommend you go back to using the original file. It has already been compressed and there is no advantage in converting them to any lossless format. It just becomes a bigger file size that has already dropped the resolution lost in that first compression.
