Hi, and welcome!

Please see the FAQ: What's a reproducible example (`reprex`) and how do I do one? Using a reprex, complete with representative data will attract quicker and more answers.

Could you edit your post to allow others to see how this comes about? It's much easier to offer answers without having first to reverse engineer the issue.
