Hi @INTREEJ
For us to have more info, post screenshots showing how your Zap steps are outlined and configured in EDIT mode in the CONFIGURE tab with the field mappings visible.
Hi @INTREEJ 
Just came across this and can see that our Support team have since got back to you. It appears to have been due to the test record from BizConnect not having any values in the City, Country, Street and Postalcode fields that were selected.
Not sure if you’ve had a chance to see their response yet, but I wanted to share part of it here in case it helps illustrate the cause of the issue more clearly:
I reviewed one of the Zap runs, and the reason the data didn't come through is because the BizConnect trigger didn't contain data for those fields.

Looking at the BizConnect Address field that’s been selected in the Mailing Street field, it seems that the entire address is contained within that field, not just the street name.
Could it be that, for that specific contact in BizConnect, only the Address field was populated and the others were blank? If that’s the case, then I’d expect that when the Zap runs live with all the address fields filled out, the City, Country, Street, and Postal Code should then be added in Salesforce correctly.
Or have you already done a live test with all the address fields filled out and it didn’t copy over all the address details as expected?
Keep us posted on how things are going, want to make sure this gets sorted!
