The new rear mechs are quite a bit different to traditional road derailleurs. If you've not already done so, best to use this as a guide -

Applies to both R9100 and R8000 rear derailleurs. Hope it helpsScott Foil RC

Just to update on the above problem for anyone searching to solve an R8000 rear mech issue like this, it's more than likely that the mech has been bolted on in the wrong position.
The mech has two lugs moulded into the casing and these fit nicely either side of the lug on the hanger. This looks how it should seat but its wrong , refer to the manual linked above and fit the mech correctly. This will then seat the mech at the correct angle allowing the chain to fit properly when cut at the correct size. .0
