span columns not working ID CC 13

Bob was right. Had to do with how I set up my master page.

That looks like a two column page, not a two column text frame.

Try deleting your InDesign Caches. This can be very helpful for fixing interface issue.

To do so:

For Macintosh Users: With InDesign closed launch a Finder Window in column view and click on your home folder. With the Option Key pressed choose Library from the Finder Go Menu. Within the Library folder find the “Caches” folder. Within the Caches folder find and delete the entire file “Adobe InDesign”. I find that deleting the cache file completely leads to a lasting change. 

For Windows Users: On Windows 7 and above the caches files are hidden. To find them go to the Control Panel and open Folder Options and then click the View tab. Then select “Show hidden files and folders” or “Show hidden files, folders or drive options” in Advanced Settings (you may be able to skip the previous steps with Windows 10). Then delete (or rename) the folder at the end of this path: C:\Users\[User Name]\AppData\Local\Adobe\InDesign\Version [#]\<Language>\Cache.

It's been working fine for me in ID CC 2018 (13.0).

You screen capture doesn't show the columns below the headline. I can't see what's going on.
