We don't really have enough info to help you out. Could you ask this with a minimal REPRoducible EXample (reprex)? A reprex makes it much easier for others to understand your issue and figure out how to help.
If you've never heard of a reprex before, you might want to start by reading this FAQ:

I still think that a reprex would increase your chances of getting help, because it would provide context and a way to test possible solutions. Even if turns out to be a bug, maintainers would need to reproduce the problem in order to debug it.
