Model Year 22/23 No radio icons on 'Favourites'

[Bear]

Hello guys and gals

I've got a 22 plate VZ2 310.

After a recent ota system update, my icons in the favourite section on the DAB radio are just plain blue/grey boxes. Weirdly though, when I swipe to get the radio station to fill the screen it sometimes reverts to the colours of the station being broadcast. I hope this makes sense...

Any thoughts or ideas? Oh and by the way, I am rather illiterate when it comes to electronic gadgetry

Thanks in advance.
