Resolved - By trial and error actually, doesn't appear to be a common problem but if it happens to you and you are reading this thread here was what fixed mine (and the problem existed on my car for weeks before I found it)
Just go to settings on the infotainment system, select system then scroll down to Delete All Personal Data and confirm. All you need to do now is go to DAB etc and set your memories again and thats it fixed. You will need to reinstall your phone in Bluetooth as well and set Home in your satnav and any other incidentals like Bass treble settings etc.
