Lister state {ls} code not working on status bar DO13

The lister state code doesn’t seem to be working on the status bar. I’ve switched it to use one of the sample status bars and it still doesn’t show SOURCE/DESTINATION/DUAL on the status bar. I’ve tried removed the surrounding {h1} tags and turning on/off the “Use two independent status bars when in dual display mode” and switching between dual/single display but still nothing I do makes anything appear for this code.

Lister & tab state -> Lister state {ls}

{sd}/{td} folders, {sf}/{tf} files, {sba} selected
{h!} ({hi} hidden items) {h!}{rpad}
{pu}% full, {df} free
{fl}
{h!}{ls}{h!}

It won't show anything in a dual-display lister. It's only for when you have two separate single-display windows that are source and destination.

In Opus 13, that also only happens if you turn this on:

Preferences / File Displays / Options / Single display Listers have source/destination modes

It was that new option that I hadn't got ticket which is why it wasn't showing up. Thanks
