It doesn't let me choose subject and content

Hey, there. I've been having the same issue lately, and I've been unable to upload any new worksheets because of this. The moment I want to add either the subject or content of the worksheet, it doesn't load any options and demands that I choose one before creating it. It just shows the usual spinning circle to the right as if it was loading the options but nothing shows up.

I am in the same boat, Jaffeth. I don't even get the spinning circle. It's just a circle.
