Watch faces reverting to default ones

I have an epix gen 2 sapphire 51

since software updated to 17.23 any extra watch faces I’ve downloaded via iq connect revert back to one of the stock ones. This usually happens overnight. 
I’ve tried switching off and on and deleting the extra faces and re-downloading them to no avail. Also tried checking them via the MacBook. 
I’m hoping a further software update will sort it. 
Has anyone else had the same issues or found a fix please?
