Issues With Putting Designs on Posters

So I have been attempting to put a 2x3 design with a 2mm margin in RGB format onto a poster product, but despite my multiple attempts to satisfy the “Optimize Designs for Poster Prints” page’s requirements, it is still unavailable to me. Waiting for a response from the help center, but if anyone else can give some insight, I would greatly appreciate it. Here’s the image in question:

The posters are not only about the correct aspect ratio. The very specific dimensions must be observed:

  • Portrait: 4724 × 7087 px
  • Landscape: 7087 × 4724 px
  • Square: 4724 × 4724 px

I hope this helps.
