Problem after last plugin update

Hi,

We use this plugin on several websites (more than 70) and after the last update we have encountered a problem.
On several of the pages, the tabs for tables, options and post types are empty.
We have tried to uninstall and reinstall the plugin but the problem is not solved.

How can we fix this isssue?

Thank you very much for your help!

Regards,
Vanessa
