Widget Problem on Home Screen

I had a weather widget on my home screen, and I had taken it off to try other weather widgets. I didn't like any of the other widgets as much, so I wanted to go back to my original choice. However, every time I try to put it back on my home screen, a message pops up saying it's already on my home screen, which of course it is not.

I have tried a number of times, but keep getting the same message. Is there somewhere else I can look to find a way to get my original weather widget back on my home screen?

Thank you very much for your help.
