Apologies - I meant the "Guidebook" section, not "Amenties". It has various sections where you can recommend local shops and services. In this case, I want to add a convenience store in the "Essentials" section.
As I start typing in the name of the store, it begins to search for the name - the dropdown list indicate sthat teh search is "Powered by Google". As the store isn't apparently known to Google, when I finish typing the name and adding my description and clicking save, the name gets converted to a similar sounding store in the area (whose adderss also gets inserted).
