Yes, it is miles between map centre and current.
Which can get down to a small value if you manually move the map.
But there is something odd in the way it centres the map on current position, so if you zoom in you are several miles away from “current position” even though the address is correct.
So yes, there looks to be some sort of issue with positioning the map, but the distances work.
I am currently discussing something similar with George, in that on page load the map centre is not set (although if you slow down the page with debug it works !) So this might be the same.
