Audi A6 C8 spacesaver issues

[JRUK]

OK, got the spacesaver wheel from the wheelshop and while it fits the hole in the boot floor, the boot floor won't close flat. The height of the wheel is the same as the boot floor on the sides, so the reinforced section of the lifting floor which should slot into the cavity, sits too high on the wheel. So there floor doesn't feel stable and is leaving a raised gap either side.

Am I missing something or has the Wheelshop sold me the wrong wheel?

Wheel by looks of it needs to sit level with the black plastic sides, not the surface level as the cover has a padding to it which is what's raising it up.

I get this - this is the issue I'm highlighting. So there is no way I can make the spacesaver sit any lower. The Wheelshop have sold this wheel on the bases it will fit.

I have just realised they advertise it it with 145/60 tyres but have supplied 145/65. I wonder I'd this is the issue?
