HA Desktop some pages not rendering correctly on tablet

Hi have an odd effect that has just started on one of my desktops in HA app on my Samsung tablet.

I have an integration for the Drayton wiser heating system. I have four rooms controlled by this system for heating. Have created a page showing the status and controls to adjust temp.

It looks like this on my desktop PC:

But on my tablet it looks like this:


Yes it’s dark mode, that’s how I like it on the tablets/phones switching to light mode make no difference.

If I edit the desktop page on the tablet it looks fine:

Also this ‘Status’ page is nor rendering correctly:

If I access the same HA instance/desktop via web browser on the tablet it’s fine.
And if I use the HA app on my Samsung phone it’s fine.

Other pages for other devices/integrations look just fine

Any help/suggestions with this please
