Code editor only shows the first character of each line. Please help me

The code editor is showing only the first character of each line. I have tried reloading, and other lessons, but the problem persists. A link of an image of whats going wrong can be seen here

Thanks for your help

temporary solution
cut & paste script into notepad, edit and copy into script.
I have this problem too :confused:

I figured out what was wrong. I was using Microsoft edge. When I switched over to google chrome it was back to normal
