Previously set materials are in an odd state, where it displays a checked checkbox for that feature, but no extra properties are revealed. After re-toggling that feature, the extra properties finally appear and the feature is observable even in the Needle runtime.
Sounds like a Unity keyword problem with 2020 / 2021 mismatch. I'll close this as I can't reproduce it; if you have clean reproduction steps on how to incorrectly get into this state please reopen :) thanks!

Needle Samples @

@package/Runtime/AnimatedProperties/AnimatedProperties.unity
And there is a example material
AnimatedProperties/Materials/Transmission.mat
on which we'll re-toggle the Transition keyword.(Transmission is enabled, but no "Transmission slider is visible") (After a re-toggle, the slider appears)
