I have been having the exact same issue as well!

The strange thing is that I had a script where it was plotting correctly, then I wrote a separate script where the issue began to occur then when I went back to the original script and ran it again to see how to fix it, the same issue had started to occur there also! So I am presuming that it was some modification to the package's configuration.... I don't know...

But I uninstalled and reinstalled again and the issue is still there....

Did you ever work out what was going wrong?
