After 5.4 update, lost Shader and Material buttons and recognition of SF

Shader and Material buttons are missing after update and re-install.

I followed the FAQ instruction, deleting folder, then installing again.

This did update SF, which is good. SF will open via Windows>Shader Forge>Load Shader and will open pre-existing SF shaders I've created.

It will not however recognize them in the asset folders themselves and no longer has any of the SF buttons to open or change parameters in the editor. Here's what it looks like with a Shader selected.

And here's what that same shader's child-material looks like

Last time Unity updated I had similar problem, but it was just limited to the Materials. The shaders themselves still opened through the regular "open in shader forge" buttons. Once I hit "compile" it allowed me to resolve things with the Materials as well. This time it is no longer the case.
