2019 Stralis Hi -Way - Weird Radio Issue

Driving the above and have a issue with the built in radio/sat nav etc - It won’t store any radio stations (saves them and then forgets them once the radio is turned off) and it won’t save my phone details. I have to go through the whole new connection process every time the radio is turned off. There are currently saved radio stations in there as well as one phone (seems like it is saving one moment in time!)and the Sat nav saves locations in favourites etc. without issue but anything i save in terms of stations or phones gets erased every time the radio is turned off (tried different phones etc. but still the same) - Minor issue but very annoying! Anyone have any ideas on a quick fix?
