I have a structure to handle page menu, from the starter tailor theme, and after upgrading to oc v3.6.12, all the links changed to a unique link as per screenshot
Tailor Page Finder not work either in structure or mixin or in global after update to 3.6.12. In ver. 3.6.11 working perfect. ( two groups of sites - each with 2 sites in a different language )
