Hi @JenniferL,
Thanks for confirming. I did have a quick look through the old Kibana GitHub issues and can't see a known issue around that version. I'm wondering if it's to do with the size of the slides similar to this pie chart issue. Can you share your chart settings, and any label settings?
Just a warning that 7.13.1 is an old version that is past EOL, so we would recommend upgrading to a supported version if you can.
Hope that helps!
