PB Editor dropdown menu bug in Joomla 4?

Hi,
When using PB in Joomla 4 and the installed TinyMCE editor, the Joomla CMS dropdown menu in the main menu duplicates the choice of field.
I've tested it on two Joomla test sites and it shows this behaviour in both. Preview also causes a 404 error.
Many thanks in advance for your feedback and hopefully a solution.

Hi
thanks for the feedback
I will check that because it shall not return a 404 error. For the duplicated entries, I know, but I have no fix for now.

please tell me the joomla version + page builder ck version (number and light/pro) so that I can check, because by my side it works
