Favourite buttons not integrating with 'My favourites' button or page

[NivoWebTeam]

Hi,

Please see here for the test pages I've been working on: https://ukfinanceteam.com/testing-internal/ and https://ukfinanceteam.com/my-favourites/

I've added 'favourite' buttons to each of the boxes (please hover over them for them to appear). when selecting the button, these do not work with the 'My favourites' button or page.

I've tried removing elementor from the My favourites page, I've removed caching from both pages.

I've added the attached code to the functions.php

Nothing seems to be working, please can you help with this?

Thanks
