BMPCC Focal Reducer Issue?

I bought the Roxsen Focal reducer, cheap I know, but it seems very sharp and up until now has been impressive.

I noticed an issue, not sure whether this is true of all focal reducers, whereby I cannot get infinity focus with an f/stop of 2.8 or below. When I set the f/stop to 2.2 the focus ring turns to infinity but wont focus on trees far away. There is not an issue, as far as i have tested, with objects closer than infinity.

I have put the lens on the BMPCC with just an adapter and there are no issues with focus. I am using a Rokinon 16mm.

If anyone has a solution, preferably not to send the focal reducer back, that would be great!
