I was curious why some El Tonics don't stack. Is it possible that some El Tonics are some form of pre-nerf that no longer drop from bday presents?
As you can see in this GIF I have 5 Everlasting Melonni Tonics. There is a stack of 2 and a stack of 3 and they cannot combine. Its like they are actually 2 different items.
I believe the ones from gifts spawned on the sixth birthday of a character are technically different items from the ones you get from exchanging vouchers for the giftboxes. So they will stack among themselves, but not with each other. Both still drop, but I guess they handle them as different items internally. In a similar way, the giftboxes themselves stack while the normal presents don't.
use the Identification Kit 
it will stack after
