Help : Setpoint in frame

[Simba]

Hello,

I made a simple addon that shows some stats like crit and attack power on a transparent frame.

I'm making a settings window to select which stats to show. Where I'm having issues is to have the stats to show in order, without leaving gaps in between.

For example, my current stats are shown in this order :

AP
Crit
Hit

If I uncheck the Crit box, I have a gap between AP and Hit. How can I make it so that Hit fills the empty space ?

Thanks!
