I think the problem is that the extractor doesn't set the zone_exp_multiplier column in the zone table, so it gets set to zero by default (probably should default to 1?)

Try:

update zone set zone_exp_multiplier = 1 where zone_exp_multiplier = 0;

Or add a WHERE zoneidnumber/short_name clause to that just to set it for a specific zone.
