Lines disappear when pasting from clipboard

I’m pretty new to Rhino and it may be a really simple issue overlooked, but when I paste an object from the clipboard into my drawing, Most of the existing lines turn invisible; I can still select them and when highlighted, I can see them. Can anyone help with this issue?

Is the object you are pasting in front of the lines, and occluding them from view?
If you change to Wireframe mode by clicking the arrow in the top left corner next to the name of the viewport, can you see the lines?

No, I’m pasting beside the existing drawing, I can’t see them in wireframe, but I can see them when I switch to to x-ray mode.

Can you post the file with the objects pasted in?

Thanks for the help guys, but I’ve figured it out. It was definitely a rookie mistake.
