Using Weird Frame Dimensions in Fusion

I'm using a Nap35 120mm anamorphic projector lens in front of a Helios 44 lens with the P6K and when I create the custom project dimensions I come up with 6114x 1980. Yes I know, its SUPER WIDE SCREEN and excessive.....,I set the project dimensions to 6114x1920 and I edit as normal after stretching the image to fit the frame.

When I open fusion the frame ignore the project settings and displays 6114x3456px ..., I guess I will use After Effects for VFX unless I'm missing something...,

Thanks in advance for your help.
