Elements missing in design when I convert Figma to HTML. What could be the problem of this and how can I fix it?

So I just got done creating a design in Figma and I was wanting to find an easier way to convert my website design to an actual website since I don’t know that much code. When I try Quest . AI and Siter . IO, a lot of my file elements disappear when I import them into the plug-ins. I’ve been watching tutorials on this and I see other people import their work into the plug-ins it comes out normally and I’m trying to figure out some parts of my design are coming out missing.
