Opacity section in Properties Panel does not inform about blend modes
If there is a blending effect applied in the opacity settings the properties panel does not reflect the blending mode. You have to click on the appearance panel or opacity to see if one is applied. Took me a few minutes to trouble shoot why an element was not visible. It would be nice if buried settings would show up if selected in the properties panel since it was designed to make the interface more simple.

O painel Propriedade perdeu sua função e "controle" na parte superior está funcionando, veja a opacidade comparada nos dois painel não coincidem
