Thanks for reaching out on the Lucid community. I'm sorry for the trouble with your document and am happy to help.
- Please be aware that the object counter in free documents will count all items on all tabs, so if you have any additional tabs in the documents, those will be counted as well.
- If that is not the case for this doc, please try to access your document in an incognito or private browsing window. Sometimes that helps with document performance issues by clearing the cache and cookies and disabling extensions.
If neither of these fixes help, please send me a screenshot of the pop-up that appears prompting you to upgrade and how the object counter on the left-hand side of the screen appears while you are editing the document.
Hope this helps!
