This is the line group that I copied and pasted

SUMMARY
When working on an image, one group of lines I had selected to copy and paste appeared at the top left of my canvas. It wasn't on a layer and closing the program did not fix it ether. Then as I was looking back and forth between two documents all of one specific color (orange) was transferred from one document to the other, having the same ghostly properties as the lines I had copied earlier. It didn't exist on any layer and I couldn't cover it or move it, as if imprinted onto my screen but covered all the layers. This bug effectively ruined my piece and I had to copy and paste all my layers onto a new document. 

STEPS TO REPRODUCE
1. I am not sure exactly how it happens but it seems that multiple instances of the image on screen are created and the one that shouldn't exist is placed in the top left corner.
2. 
3. 

OBSERVED RESULT
An intangible duplicate of ether a segment of lines or all of one color on screen becoming locked on top of the canvas.

EXPECTED RESULT
An absence of freaky ghost copies ruining my canvas.

ADDITIONAL INFORMATION
For the line segments I had copied and pasted I was luckily able to shrink the canvas to below where the lines were, but the lines did not disappear like any other lines or color that exceed the canvas.

That is probably a reference image. Try switching to the "Reference Image" tool and remove it from there.

OMG it worked. For some reason it is creating unwanted reference. I see that there is a shortcut (Ctl+Shift+R) for Paste as Reference Image, but I had only pressed Ctrl+C and Ctrl+V. Though I don't know why it would copy a selection of color from one document to the other without my knowledge.
