I’ve double, double checked the latlong value (50.790219, -1.037997) and am comfortable it’s correct… even though it displays a 3rd different way in Google maps
We understand that the pin is not pointing at the correct location due to its size.
Our team has checked your application and the pin size increases when the column is set as the header column.
We would like to provide you with a workaround for this issue.
We would suggest you create a format rule for the header column and adjust the size according to your requirement.
