Issues with Photo Box and ACF in Wrap Loop

Hi,

Can you please assist me with the following issues?

Photo Box issue:

When I use the Photo Box element, the Title link feature is not working.

The title is not linking to the URL that I specified in the editor, and there's no <a href> element generated:

There is no a href element on title:

ACF problem in Wrap Loop:

ACF definition:

The thumbnail is not displaying, both in the editor and on the frontend:

I uploaded the thumbnail into the ACF field for the "Atopijski dermatitis" category:

It seems that ACF is not being loaded properly, as I have tried multiple ACF fields, and none of them seem to work.

I used this structure: {acf:thumb_kategorije}.

Could you please help me resolve these issues?

Thank you and regards
