Infernal Minions Sound bug

Hello,

I have encountered a sound bug with the Infernal Minions Support Gem.
I have a 1 min video available, unsure how to add it here.

Currently I am trying to slot the Gem into ' Skeletal Warrior ' combined with the support slot ' Last Gasp ' and ' Meat Shield '.
I have found this triggers when combined with 'Meat Shield', 'Fire penetration' or other support Gems that affect damage done or stat changes.

The description of 'Infernal Minions' reads :
• Minions fro; supported skills take 20 % of their maximum life as Fire damage.
• Minions from supported skills ignite enemies withing a radius of 1.5 metres as though dealing Base Fire Damage equal to 20% of minion's Maximum life.

The description of ' Meat shield' reads :
• Minions from supportes skills deal 35% less damage.
• Minions from supported skills have 50 % more Maximum Life.

I am assuming this has something to do with the maximum life affected but unsure if it's the fire damage taken from their life or dealt to enemies.

Hoping this is sufficient information for you to work with.
Have a pleasant day and Happy Holidays!
