Lingering Illusion - Support Gem Issue

I'm a level 74 Invoker Monk, and when I apply certain support gems to the spirit skill "Lingering Illusion" it stops working (although it doesn't say it's disabled or "not enough spirit reservation"). These support gems are specifically "Vitality", and "Herbalism" of what I've seen so far.

I've confirmed I have enough additional spirit for the skill. I have 115 max spirit reservation, and after I apply these support gems and activate the skill, I still have enough spirit leftover. Though, if I deactivate my other skill, "Herald of Thunder", it starts working again.

Specifically I have "Lingering Illusion" and "Herald of Thunder" activated, with the support gems "Cannibalism" and "Vitality" and when I roll no illusion appears. But if I remove "Vitality", the illusion appears again when I roll.

Yup. I was trying Lingering Illusion + Vitality + Clarity, and nothing was happening despite there being an icon in the top left of the screen. All the Spirit for the supports was reserved as well.

When I took off Vitality, immediately it now works.

Only other persistent buff in use is ElementalInvocation + Conductivity + FreezingMark. If i turn it off, immediately Lingering Illusion works even with Vitality.

I tried changing the order of the persistent buffs in the 9 skills list, and it's the same behavior no matter the order.
