Thread text between columns not working
Hi! During a class I was teaching today on InDesign, I went to show how to thread text from one column to another. However when I clicked on the out port, I received the below box instead of the text in the cursor!

I then tried to find via a right click another option to do a thread, but was unsuccessful. I really hope this is a bug! I have not changed my settings, so I have no idea how this happened.
Is there a way to change it back to doing a thread or is there another way to thread text. Any help is greatly appreciated!
