Glossary Cleanup Fatal Error

Installed the plugin, added a term, and (probably my own fault here) I saw a second glossary page had been created (mysite.com/glossary-2). Deleted the second page, and got a bunch of errors which I didn’t save…looked like it was trying to find the glossary page and couldn’t.

Attempted to cleanup the data by using the “Cleanup Database” button, and I see these errors:
Fatal error: Uncaught Error: Call to undefined method CMTooltipGlossaryBackend::cmtt_getGlossaryIndexPageId() in /home/mysite/wp-content/plugins/enhanced-tooltipglossary/backend/cm-tooltip-glossary-backend.php:495 Stack trace: #0 /home/mysite/wp-content/plugins/enhanced-tooltipglossary/backend/cm-tooltip-glossary-backend.php(143): CMTooltipGlossaryBackend::_cleanup() #1 /home/mysite/wp-includes/class-wp-hook.php(286): CMTooltipGlossaryBackend::cmtt_admin_options(”) #2 /home/mysite/wp-includes/class-wp-hook.php(310): WP_Hook->apply_filters(”, Array) #3 /home/mysite/wp-includes/plugin.php(453): WP_Hook->do_action(Array) #4 /home/mysite/wp-admin/admin.php(224): do_action(‘cm-tooltip-glos…’) #5 {main} thrown in /home/mysite/wp-content/plugins/enhanced-tooltipglossary/backend/cm-tooltip-glossary-backend.php on line 495
