Hand of Chayula Only Applying First Socketed Curse

What title Says. The curse above the targets head is always the first one socketed, and the monster only shows this one on their debufs. Switched curses to check, and its always first one socketed. Might be just the display is wrong, but I think its not applying all marks. My specific case is a 3 link hand with the three resistance curses socketed.

Even though you can socket multiple curses in HoC you are probably still limited by your max amount of curses active. Do you have any bonuses to your max curse amount ?

If not, this is most likely the issue since you cannot have more than one curse per target unless using passives or gear to increase it.
