Social importer changing postcode

Hi

First of all I have to say that I love the social importer. I think it is a great great plugin.

I have disabled the “Google address autocomplete” and the “set address on map from changing address fields” and all my problems with the addresses been changed have been fixed (https://wpgeodirectory.com/support/topic/address-changes-when-clicking-set-address-on-map/#post-21651)

However when I use the social importer the postcode is still modified in some of the listings. For example:
https://www.facebook.com/events/1387237568236160/?ref_dashboard_filter=upcoming&source=1

The postcode is changed from N2 0TH to N2 8DR. However if I inserted the same event manually the postcode would not be modified.

Any suggestions??

Thanks in advance
