Hello Support
Thank you for latest build update 3.7.3 for Jlex Comments.
I have installed new update and cleared the Joomla cache, however there is now a new problem.

The label for a Guest (Public) comment is now displaying, however it is incorrectly displaying as "Webmaster" instead of "Guest". I did double check the settings in Backend for User Group = Public.

I have attached a screen shot from one of my tests and also showed my settings.
An actual Webmaster account is working correctly.
An actual Member account is working correctly.

Regards
Derek
