I've never run into this before and have done all the troubleshooting I know to do...

When I type out text by hand into the body of an article it shows up correctly in preview and all views.

If I copy text from some other source like a word doc, HTML doc, even a .txt file; everything after the first line break is not showing up. I've tried reformatting the text, moving it to different programs, changing the "text format", editing it in source view and no matter what I do it won't show up in either preview or saved/published.

Is there some known issue with hidden characters copying over and causing issues?

Am I missing something here? I'm sure there is something completely simple causing this issue that I'm just not catching.

I'm running core 8.0.2.

Best, Rob
