After making a component the content vanishes

after making a component the content vanishes. it is found to be at another position when zoomed out. HELP!

Can you show a gif or images that describe what’s happening with you?

sorry, images wont be possible.
ill try and explain,

i made a rectangle, extruded it. when i make it a component, the contents of it vansihes from its original position…

further, when i zoom out, i find the contents in another location.

Without clearer images, or even the sketchup model, I think it will be
difficult for someone to help you. Sorry!
