USS unit warnings on import

[ptbarnaby]

Shows numerous warnings on import (Unity 2020.1.14f1), e.g.

StyleSheet import: type=Validation, code=InvalidProperty file=Packages/com.av.smart-hierarchy/UI/preferences-style.uss:3 Expected (<length> | <percentage>) but found '6' padding-left: 6 -> Property expects a unit. Did you forget to add px or %?

StyleSheet import: type=Validation, code=InvalidProperty file=Packages/com.av.smart-hierarchy/UI/popup-window.uss:21 Unknown property '-unity-slice' (did you mean '-unity-slice-top'?) -unity-slice: 1

I just noticed that there is "Disable Validation" toggle on StyleSheet assets. They won't bother you anymore 🙂
