Some issues ... Lightbox and Gallery

Hello to all!

There are some issues with the page builder:

Pics: By using the lightbox the title is not shown in every popup. The settings for the pics are all the same, but some there are dome without title.
Also changes were not save, e.g. switching from "lightbox" to "no lightbox" doesn't fit evertime.

Gallery: The gallery produces a lot of warnings by using the option "from folder" (see attchment)

It would be nice if there is a solution.

Hi

Please check what is your PHP version and tell me, if you are working with PHP 8.1, please try PHP 8.0 and tell me if the messages are gone
for Pics issue, please give me the url of a page where I can see the problem
