On Tab breaks site options behaviour

Hi Team

I am attempting to disable all automatic address filling where possible as the google address api data and my country doesn’t mesh very well. Hence I:-
1 – Disabled Google address autocomplete?
2 – Show all locations in dropdown?
3 – Allow set address on map from changing address fields
4 – Disabled move map pin from changing address fields

I have achieved my objective except when on adding a new listing I must “click with my mouse” instead of using “Tab” out of the address field.

Once I press tab on the keyboard, the application attempts to find the address and breaks my region & city list and display nothing.

Please note that if I use the mouse and click the appropriate field, there are no problems.

You can attempt this via page https://www.trinigo.com/trinidad-tobago/info/contribute/

Thanks
