Thanks for your comment.

Bizarrely, the dashed underlining of the address on the dropdown only appears on my iphone, not on my mac (both browsers are chrome).

I have tried to use some html / css but this is all new to me. I have tried to use the text-decoration: none with #nodashedunderline as the name of an ID attribute and then applied this to the relevant element but it’s not working.

I don’t know how to code!
