Can't add number to street when adding a location

When I create a new location and I write the street and the number, a menu is shown with the different possibilities. Once I click on the first that matches my criteria, my string is replaced with a long string that doesn't have either the street name nor the number.

Then when I click show on map I'm not sure if it's taking a random point on the street, or if it's using the correct building number.

Thanks :)
