Leading zeros for more than 99 songs

I use MP3Tag v3.31a (64-bit) on two computers. One computer runs Windows 10 and the other runs Windows 11.
In Windows 11, there is a problem with leading zeros when there are more than 99 MP3 tracks.
1 should become 001, but instead becomes 01.
In Windows 10, it works fine.

I do not see that:

where do you see the missing leading zero?
How do you create it?

I use the autowizard (screenprint below).

Then convert via File name - Tag. The result should be Kayak - 095. Ruthless Queen (screenprint above). With Windows 10 it works fine, but not with Windows 11.

Do you mean Tag-Filename?
Which Format String do you use for the conversion?

See screenshot:

$num(%track%,2) sets the number of padding zeros so that 2 digits appear. This means that you cut away the leading zeros for 3 digits.
Use $num(%track%,3) instead.

I see it now. Sorry for the inconvenience.
