Scheduler widget links not working

I added a custom text field in wordpress scheduler settings page and now I can not delete it and the links in the widget in the sidebar, do not work. They write the correct link in the bottom of the window, AND in the address field at the top of the screen, but there is no change in the calendar on the page.

I have uninstalled and reinstalled fresh multiple times to no avail! :frowning:
