Moving Recorded Screens Down (after changing screen size)

Hello!

I used to record my screen simulations like this:

• Record at a dimension smaller than required
• Resize entire story to actual dimension after the recording was finished
• Tell Storyline not to "resize," but instead, shift elements down

This way, I had a blank white spot at the top of each screen, where I would put my header.

I don't know when this changed, but I can't shift the captured screens downward anymore. It instead puts a gap on the top and bottom of the slide. Or if I scale to fit, it puts the gap at the bottom instead of the top.

How do I move the background downward now?

Thanks for the help!
