Death State on Condition not working

[Kryptor]

Using PF2e 1.10.17.2355,
foundry 0.7.8
healthestimate 2.4.0

The other options on the mod work perfectly, but setting Death State on Condition to true and leaving Death marker on the standard "icons/svg/skull.svg" (I've checked with console that it's the right condition icon from the death marker on the combat tracker). Marking defeated in the combat tracker doesn't set the marker to Dead.
