[X] Problem with leading zeros in the TRACK tag

No, I did not say hexadecimal, but octal.

Ok, this is one way to go, but needs to do it by two filtered steps.
Another way to go would be to modify the tag-field TRACK, after importing the number string having the leading zero, by an action "Format value" using the format string: $num(%TRACK%,1).
