TI wishlist is not compatible with Advanced Product Fields by studio wombat

I installed the Advanced Product Fields plugin to add custom fields to my products. However, when I try to add a product with custom fields to the wishlist, the wishlist page displays something like this:
wapf :{"field_65d5e59350dd9":"1","field_65d5e55772826":"1","field_65d5e5aabae49":"1","field_66cae1816539f":"1","field_66cae18cd74f0":"1","field_66cae19f08b11":"1","field_66cae1ab2e16a":"1"} instead of the actual custom field values.
