Variables showing on screen in Windows 10 IE11

Variables show in red for the following...

• Inventory,
• Decision Tree,
• Media Lesson

...when project created in other OS (e.g. Windows 7, OSX) is edited in Windows 10. (This is what the behaviour suggests to me, although I can't say 100% that this is the circumstance that causes this error.)

Please see the attached image

Apologies--I just realised that this is probably because I had 'Author Support' turned on!

Thanks Candace for letting us know.
