As a rule, no 0 EUR bookings should appear during import. In most cases, this is an error in the assignment of the fields in xentral. Check again the settings of the bank accounts under Administration → Settings → Accounting → Business accounts.
Possibly the bank file still contains blank lines or information lines after the last bank entry. These can be truncated by entering the number of lines to be truncated in the "Ignore last lines" field:
However, there are also banks that now and then have their own posting with 0 EUR e.g. at the end of the month on the account statement. This can be booked e.g. as import error, if the following accounting program cannot read in zero values. In this case, this line will not be included in the export from xentral, but will be "cut out".
