Hello, We plan to use authorities linking and hierarchy in production to display thesaurus based topical subject authorities. On a clean install of Koha 3.22 on Ubuntu using UNIMARC, we created 1 biblio with 2 topical subject authorities (biblio unimarc 607), the one being broader than the other and linked them. Issue #1: authority link relations had to be entered manually (in 550$5 'g' and 550$5 'h') as they would not be entered using the authority finder plugin. Issue #2: only broader to narrower terms show correctly when viewing the broader term's details with a collapsible + sign to display the narrower term, while in the narrower term's details view no broader term is displayed as linked. Any guidance will be greatly appreciated, Andreas
