Ansible facts unmatched contstraints

Problem: Some Ansible generated facts are not visible from the host’s facts page. Attempting to change pages to one where such a problem fact exists triggers and Oops warning, such as
No route matches {:action=>“index”, :controller=>“fact_values”, :host_id=>“foreman.my.domain”, :parent_fact=>“partitions::/dev/mapper/rootvg-var_lv”}, possible unmatched constraints: [:parent_fact]

Expected outcome: Should be able to view the facts

Foreman and Proxy versions: 1.18.2 (on CentOS 7) and 1.19 (on Ubuntu)
