GroupInitiative for roll 20 not working

[darkcalel]

working on trying to use Group Initiative for roll20. As I try to roll for a group of creatures its rolls for them all but doesn't roll a d20 even tho it seems to show it in the chat. As of right now it basically shows when hovering over the chat for the characters i rolled on,
Rule#1
1d20} +5.25 (i had it add the dex mod and tie breaker)
5.25 (only shows the modifier as the final outcome like its not rolling the d20)
()+5.25
