ITU Zones with leading 0 (Zero)?

Norm - KC1BMD

For some reason after importing my HRD logbook into DXK I noticed that some ITU Zones that would ordinarily have a single digit contain a leading 0 (zero). There are no errors shown when pulling up the QSO in DXK., Is that going to cause any issues down the line for anything? If so, can someone suggest and easy way to search for these and correct them?
