URL and Lyrics Tags missing and deleted after edit in wavepad

Support
1

I use a programm called Wavepad from https://www.nch.com.au/wavepad/de/index.html
there is a URL tag which I use to store download links.
also a field containing lyrics is available

I can't find thie URL tag in MP3TAG
sometimes the lyrics is deleted when editing the tags with MP3TAG

does anybody also use wavepad to edit MP3 files and can reproduce this errors?

What have you done in MP3tag to verify that the data is missing?
Also, what do you mean by

What is characteristic for these times?

there are two problems occuring in my scenario
First when I edited a MP3 file and entered Artist, Title, Year and Genre. I used the comment field to enter a URL (youtubr link). Then the MP3 file was saved. Then I switched to Wavepad, corrected the volume and inserted the lyrics. Then I entered the URL into teh URL tag in wavepad and saved the MP3 file again.
Then I switched back to MP3TAg and searched for the URL. I detected that the comment field was truncated by wavepad. Again I entered the URL into the comment field, saved the file from MP3TAG and switched to wavepad. There I found again a truncated comment and
that the lyrics are deleted.

The truncation of the comment must be a bug of wavepad, I reported this already to NCH

I have also found that the lyrics will not be deleted every time, I have not found what is the reason and how to reproduce this

It looks to me like this a wavepad issue.
So the Support section would be better.

a short consultation with @LyricsLover shows that wavepad destroys existing tags, adds a v1 comment to a v2.x tag truncates and deletes other fields.
I would not use wavepad for tagging in the current state.
