problem with Branding Agency template

Please see the hidden content.
This is a page that I am creating as a test and trial page for the homepage of a new website to be set up. You will find the page called TEST Thank you in advance for your efforts!

Sorry, now it must work!

I don't understand that at all! I can simply log in with the login details provided to you. Can you try again?

Very strange, when I log in with the Joomshaper account I can just open the pages!

Hello Mehtaz. I now notice that when I get to the page, sometimes both fields in the slideshow are not readable, and other times one of them is readable and the other is not. When I reload the page in the browser, everything is as it should be. So it seems that the page is not loading quickly enough in Chrome. Is there anything that can be done about that? I like to hear from you.

Hello Mehtaz.
It concerned the page below

But after your last message I got the message that an update to PM 5.3.4 was available. After that time I haven't had this problem anymore. I still have a problem on a two-page spread that I made with this template.

On this example page that I modified, there is a TAB function with some photos. I cannot edit it in front editor, but I can edit it in the text editor.
