Render a list with a custom format doesnt work

[svonjoi]

template: "list" format: "{created}: {title}"

doesnt working for me. Still printing only title in list

UPD. working these way. Its interpretate template "list" as "table" template: "list" fields: ['title', 'created']

Another thing.. Is possible change the output date format? Using {{created} or {modified} printing something like this "2021-12-13T11:33:16.952Z"
