Excel 365 Insert Map - No Southern Ireland??

Hi All,

I've created a map using the Excel 365 feature 'insert, map'.

The issue I've got is I can't get excel to plot southern Ireland on the map - Please see picture below.

I've tried using postcodes, counties, co ordinates with the insert but, but every time it plots fine, but southern Ireland isn't there.

Can someone let me know how I can do this or a way around this please?

Thanks,

nathan
