Hey there.
The way spare parts is worded creates a considerable inconsistency in the game for no good reason whatsoever.
The issue is that spare parts is a buff (green) and not a status effect (blue) for example.
When a character dies the buffs dont persist through defeat (unless stated otherwise) there is nothing new there. Revive cannot be prevented, all cool. The dying character loses the spare parts, all is well.
Now the problematic part is that spare parts orders other spare parts buffs to be dispelled which is also fine, it can order whatever it wants to order.
But spare parts cannot be dispelled. It is in the description.
So here comes the dispel effect, goes up against the dispel immunity... and wins??? Like, how?
Based on EVERYTHING in this game the correct function would be that the character dies, revive is triggered, the dispel is triggered then the dispel doesnt happen on the other characters because of the immunity.
I think I do unterstand the intention behind the kit, but you are creating contradictions and inconsistencies without good reasons.
If you want to get rid of a locked, undispellable buff you should definitely use the term "remove" as it was introduced in the general skywalker kit. Remove is a higher function and it can bypass the dispell-immunity. Or just make it a blue status-effect there are different rules for those.
As of now, removing a dispel-immune effect with a dispel effect is just flat out a bug.
