PHP 7.4/Joomla 3.9 error: Undefined Property in Backend

Good afternoon LS team. We installed the LS Cache and it is improving performance on our site. Thank you for your work on this plugin.

However in the back end, we receive errors like this:

Undefined Property: Joomla\CMS\Table\Module::$element /path.../plugins/system/lscache/lscache.php:702

This is being called via ajax upon making some content updates via a module called 'RokCommon' The ajax call is failing because of the exception being thrown in the lscache.php execution.

We are using Joomla 3.9.22 (stable)
PHP 7.4.32
LS V8.0.1 Cloudlinux 1.3

Any advice on how me might troubleshoot or resolve this would be much appreciated.

Best regards
