Aye it's the same with the reporting here. I would call it Derry the odd time depending on who I'm trying not to offend. Referring to Northern Ireland as 'The North' seems to becoming more prevalent in the media. Although, I would never refer to Northern Ireland as 'The North' as that's complete b_ollocks.
All that aside Northern Ireland has come a long way. Great country, steeped in history & peaceful. Some trivial issues shouldn't detract from that.
