Location Column - Exact Address not Correct

We have a board which is for all of our incoming custom requests.
The account manager fills a form in, which in turn fills our board in.

We have an address question, which is created using a Location column on the main board. This is where our account manager would like the sample sending to.
When we type in the address, starting with the house number, it does not show the post code. If we type in the post code, only the street name is shown and we cannot select a door number.

Is there any way of getting around this or do I just need to convert it to a text column to make it easier.
