Failure to delete and replace tags

[remenor]

I was able to compile in Debian 10 but there are some faults when trying to delete tags:

--remove-everything does not remove tags

$ metadsf --remove-everything 01\ -\ Jeff\ Beck\ -\ Led\ Boots.dsf segment violation
--set-tag or -s does not replace the tags but adds another of the same type

metadsf -t 01\ -\ Jeff\ Beck\ -\ Led\ Boots.dsf TIT2=Led Boots TPE1=Jeff Beck TALB=Wired TCON=Pop TDRC=2015-16-08 TDAT= TRCK=1
metadsf -sTIT2=New --id3v2-version=3 01\ -\ Jeff\ Beck\ -\ Led\ Boots.dsf metadsf -t 01\ -\ Jeff\ Beck\ -\ Led\ Boots.dsf TIT2=Led Boots TPE1=Jeff Beck TALB=Wired TCON=Pop TRCK=1 TIT2=New TDRC=2015-16-08 TDAT=
Delete and add the tags individually works perfectly
