Yoast breadcrumb broken

Because of an issue with another plugin I was asked to temporarily disable all the other plugins I use. This I did and it included the GP one.

However, I've now turned them all back on and my Yoast breadcrumbs seem to be broken.

They are now replaced by the following, which I guess is some broken code of some sort

','

' ); } ?>

You can see it on my website at https://www.suddencardiacarrestuk.org/information/cardiac-arrest/agonal-breathing/

Thanks
