timeline resolutions changing

Hi, trying to create 2 25fps timelines. One is 970x250 and the other is 300x250, and no matter what I do, the height comes out 256. aaaargh!

Davinci 16.2.7 on iMac Pro

i have a few questions before I might be able to help you.
first, were does the resolution come out to be 256? in your timeline? in the final export?
seccond, whats your project resolution?

Resolve can't go under 256. You may need to scale or crop in an external program.
