Hi Kuz

That's interesting.
On page 9 of the manual for the Esprit it says to have exactly 75mm

But it looks like they aren't including the back end of the corrector itself, which is both in your image, and their website.
Your ZWO filter wheel I think is 20mm,
So that would be:

Camera Flange to Sensor = 17.5
ZWO filter wheel = 20
Additional spacer = 16.5
meaning the extra bit at the back of the flattener is 21mm?

I've only got a 21mm spacer, a 16.5mm spacer so will likely need another spacer, but at 20mm..
