[EE4] URL Title Error Won't Resolve

After adding content to page and forgetting title and url title, I hit submit. Both the title and url title threw errors on the inputs as expected. After adding a title, and the url title auto populating, the error for the title disappeared but the url-title remained an error. I was unable to get rid of the error after manually editing the field, tabbing out of it, clicking off it, reediting title, etc.
