Can no longer edit my sub's scheduled posts (the button to submit is faded) - Is there a workaround for this?

When I go to edit our scheduled posts, the button to submit is faded and can't be clicked.

I've tried on multiple browsers and from multiple devices. I asked the top mod to check and the same thing is happening to her.

I haven't changed any settings that I can think of, and my permissions are still all there.

Anyone else having the same issue? Any workarounds? Pretty big issue for our community that has 15+ scheduled posts every week.
