Opigno 2.13 Catalogue page white

Hi I have updated from 2.11 to 2.13 and have an issue with the catalogue page displaying white. composer.json was updated drupal/slick - removed kenwheeler/slick - added The composer updates installed successfully. Further investigating within Chrome the Catalogue page's opacity is set to 0, changing this to 1 everything is there as it should. Does anyone know how to fix this?
