The layer blends in 21.2 upgrade no longer work

I just upgraded to 21.2 and now the layers do not work properly. The blend modes do not work anymore and I cannot view the individual layers. When I turn off a layer to view a different layer nothing happens. When I turn off layer one to view the background layer nothing happens. It still shows me layer one and not the background layer. I cannot do my work without the layers working as they used to before this upgrade. How do I get rid of this upgrade?
