Is anyone else encountering issues w/ being insta-killed out of wild shape?

Playing multiple co-op campaigns, and every druid across multiple campaigns experience, randomly, unexpected deaths when being knocked out of wild shape. Not death saving throws either - straight into full blown d-e-a-d.

Per the rules, it should go from wild shape -> spill over damage being removed from the remaining HP of the druid. Reading the combat logs we see that while enough damage is done to knock the druid out of their wild shape, the remainder is not nearly enough to put them into death saving throws, let alone outright kill them.

Is anyone else encountering this issue?
