Change A Page Format

[mipi]

Dear Dorico Friends, could somebody explain me please how do I change a paper format on existing project? I think it was set to DIN 4 from the very beginning, but the output in write mode is like in a picture below. When I print the score, it has a wrong format as well, but parts are in correct DIN 4 es expected. Here is a .dorico file as well. I’ve never had this issue before. Did I set something accidentally as a default?

Of course, I set it probably by the accident. I was searching on a wrong place - preferences - general - default paper size type. Thank you very much. Solved
