missing field itemlistelement breadcrumbs

hey guys,

I wanted to check out the position of search terms leading to my website using the Google Search Console. I then noticed that “position” does not show up in my list and it only shows me clicks and impressions under “queries” – this led me to the following error regarding the breadcrumbs on my site, hopefully you guys can help?

@type BreadcrumbList
itemListElement	
A value for the itemListElement field is required.

The Yoast Support confirmed that this is coming from my Choco theme, which is sadly not supported anymore. Hopefully someone here can help me out though with your expertise? ??

Maybe it could come from my ZOOM social icon widget?

Looking at the line shown for the error “A value for the itemListElement field is required.” in line 43 shows this, followed by more code:

href="https://www.twitch.tv/towertak3r" target="_blank" > <span class="screen-reader-text">twitch</span> <span class="zoom-social_icons-list-span genericon genericon-twitch" data-hover-rule="background-color" data-hover-color="#9e5ae2" style="background-color : #8224e3; font-size: 16px; padding:5px" ></span>

Could it somehow be due to the Zoom Social Icon widget or is it just a coincidence?
Thanks!

Thanks so much!

Cheers,
Chris
