Custom Resolution Project Setting issue

I'm working with ARRI media shot at Alexa XT 1.55 resolution (3414 x 2198) but generating a timeline based on one of these imported clips results in a default 1080p resolution. When I go to start a fresh project, head into the project settings and opt to punch in my own custom frame size, the x dimension allows me to enter in "3414" but the y coordinate only lets me type in three digits and not four. Essentially, it only allows me to create a 3414 x 219 frame size. What gives with the missing fourth digit? Am I misunderstanding how the custom preset works?

What version of Resolve are you using? The free version only allows up to UHD resolution.

Ah, then that would be my answer. I'm using the freeware version. Time to upgrade!
