The Source theme doesn't show posts on websites with custom routes

I have a similar issue with the Source landing page theme on Ghost(Pro) where the home page does not filter the posts anymore as defined in the routes.yaml. Additionally, neither on the separate collection (“newsletter”) neither any tag or author page do all posts load properly. Ghost cuts at 16 posts and does neither load continuously when scrolling nor displays a “See all” button.

routes.yaml:

routes:

collections:
  /newsletter/:
    permalink: /newsletter/{slug}/
    template: index
    filter: tag:hash-newsletter
  /:
    permalink: /{slug}/
    template: home
    filter: tag:-[hash-newsletter]

taxonomies:
  tag: /tag/{slug}/
  author: /author/{slug}/
