The workaround for this is to amend the draw time to 0.1sec with no hand and then the words still pop in quickly but don't encounter the problem on render.

It could also be that you have 0 second Move-in elements. When you have an element set to Move-in that has a zero second animate time it can appear in the wrong place or not appear at all on the rendered video.
