Members List Plugin in wrong order?

Hi WordPress folk!

I’ve tried and failed miserably to set the ‘Members List’ plugin to display members as I would like. Ideally, it would shuffle the member list and show a new group every time, but no meta seems to do that.

I could settle to have the newest members displayed at the top, but when I use activation_key or lastvisit, it always (whether set to ascending or descending) shows the earliest registered members first.

If you know an option to make either of these work (random or newest first), it would be greatly appreciated. The page in question is https://www.captainplanet.me/planeteer-profiles

Thanks!
