I don't see any improvements to the question
Someone else suggested an edit. Until the edit is approved or rejected, you won't be able to see it.
The hover-text on the disabled edit button hints at this, but doesn't say it explicitly:
Another edit is awaiting approval for this post. Further edits cannot be submitted until the pending edit is reviewed.
