Some elements like search bars, back arrows, and text aren't showing up in my prototype?

Hi everyone! I’m new to Figma but can’t seem to figure out why some of the things I created like search bars, back arrows, and text boxes I designed won’t work in the prototype. Can someone help me with this? Thanks in advance. https://www.figma.com/file/iGKNdg2jw4A4zuKqXBZewe/CoffeeHouse-Project?node-id=0%3A1&t=VQ5dnxIRUvS2EQ9c-1

I have looked at your screens in Presentation mode and all objects are displayed.

I figured it out. For some search and text bars I for some reason just had to bring them out and back into the frame. For the back arrows, I replaced them with different ones. Thanks for looking into it.
