I've added title override %1, to contextual filter. Filter uses taxonomy to get nodes.
If I open page "catalog/1" I get title from term1 with all the content If I open page "catalog/2" I get title from term2 with all the content But if I try "catalog/1+2" I get title "No name" and the content for both terms.
How to define page title as title of first (any) term in the filter?
Upd it appears that there's a problem with title override. If I add title override %1, then I have "No name" title for multiple terms...
