Cannot prototype... frame moving undesiderable

Hello guys, pretty new to design and more with prototype. I’m learning on a project for an App and now that I have finished the draft for the design I’m trying to prototype. My first issue is that the frame and the elements are moving around the screen (of the mobile phone) without that any scroll was added.
In practice is like all the frame is not fitting the screen, so whatever interactions I add simply didn’t work, because all the elements keep “floating” around.
I tried to check if I added some wrong setting but I couldn’t find the solution.

Hope I explained properly…
