Axes in the Input Manager are blank

I opened the “Axes” dropdown to try to modify it, and it was completely blank. I think the attached image is pretty self explanatory. I’ve never seen this before, any ideas how to fix?

I’m seeing the same issue. Did you ever find out how to fix this?

You can create a new project or open an existing one, and just copy paste the values into you project
