SRS main skill - Support minion Combustion - Debuff Indicators

Hello,

I would like to know if my assumption regarding Combustion support are accurate and would be very thankful if someone could confirm or correct them.

I am using SRS as main skill, pure fire damage. I also use Raise Zombie linked to Combustion and have flat minion added fire damage on Jewels.

According to the Wiki for Ignite:

"

Each ignite effect remains present on the target until it runs its course, but only the one with the highest damage per second will cause damage at any given moment.

Therefor I assume that if my SRS and Zombies both ignite the enemy, only the SRS Ignite will do damage, since it is the higher damage one, but the Zombie Ignite is also registered on the enemy, lowering the Fire Resistance by 10% due to the Combustion support.

I am also using Tukohama's Vanguard Spectre that should apply the Scorching Ray Totem Fire Exposure that should be independent of the Combustion Support. And my self cast Flammability Curse should lower the resist even further.

Are my assumptions correct? Or am I misunderstanding something? Unfortunately I heard different things so far. According to a Reddit post someone tested it with conflicting results. So I am not sure.

I also heard in a video or stream, cannot remember where, that there was, or maybe still is a bug regarding Combustion Support. Is this true or does anyone know specifics?

Furthermore, how do I see if the enemy is effected by Exposure and/or Ignite? The Curse I can see due to the Icon above their head. Under the enemy health bar there are two sets of icons. One set on the left (maybe debuffs?) and one on the right side (possibly buffs/resistances?). Due to my Skitterbots I can also see bigger Shocked and Chilled Icons in the middle, in a different art style. I would assume, that Ignites should be displayed the same as Shocked and Chilled, because it is an elemental ailment as well. But I have never seen an Ignite Icon in the middle. But I have seen a little flame icon on the left side from time to time. Is this maybe the Exposure indicator? Is ignite maybe only indicated by a burning model of the enemy?

Thank you for your answer.

Kind Regards

Edit:
I made a video to get a better look. I think the small Icons on the left and right are resistances (low on left side, high on right side), because in the beginning of the fight the enemy had all four on the right side and the Fire one kept flickering (blinking from one side to the other). I would assume that is due to ignite overrides maybe and then when the exposure of the Scorching Ray Totem kicks in it is stable at a lower point and displayed on the left? But the flickering would indicate that something with Combustion is maybe not working 100% correctly? Otherwise it should stay stable on the left side and not change sides 10 times within two seconds. Unfortunately I do not know a good free image hosting site, otherwise I would link the screenshot.
