Using Filter on My Population on any page other than first returns error

Searching with Filter on My Population from any page other than the first page of names gives an error

For example, on the second page of names in My Population I filtered for xxxxx family name and was shown this error:

Error: The requested address '/registry/co_people/index/page:2/co:2/search.familyName:xxxxx/op:search' was not found on this server.
