Can't create more than 1 custom attribute without closing/reopening

[Cricitem (webTAC | Technology Apprenticeship Center)]

This is happening on all of my projects. I’m using Chrome 55.0.2883.95 on Mac.

When I add a custom attribute like a title to an image, or anything else, I can’t add another custom attribute to any other thing until I close the project and reopen it. I’ve tried restarting my browser and even the computer.
