Edit Sore Details

I can edit store name but that is the wrong flag it should be a UK flag not sure how it got there but I’d like to change it. I am in the UK and registered for UK store and it shows UK in my account just not here not sure how it effects anything but worrying for a newbire. Any tips very welcome TIA
