the submenu no longer scrolls after installation JUX Portfolio

Hello,
Thank you for your extension JUX Portfolio Pro. I bought third time, extension is perfect!
But this time I use for joomla 4 site and I have problems.

I have 2 problems, if you can help me, please!

1. As soon as you click on gallery photo and you are redirected to the detail page, the submenu no longer scrolls.
On the other pages submenu works well, it's only on the detail pages of Portfolio

jQuery library loading : I tested ON and OFF, the same problem.


2. In the detail page, if I click on photo, it does not open in pop-up, but on the black background.
I would like it to open as a popup.

Could you help me, please?

Found it! Global Site Configuration, Default List Limit, it's work !
