Prototype glitch

Hi there!

I am having what seems to be glitch with my prototype, which I haven’t seen before. When I fix the position of a frame or component on my screen, some of the lines/strokes disappear when I view in prototype mode, but I can see that they are not effected in my design file. I can’t figure out what the issue is. See the images below for reference.

Any help is much appreciated!

Here’s what the screen looks like not in prototype mode. As you can see, the line and comment button cut off partially.
