Shadows on Translucent Materials

Anyone can point me to any in particular that I might have set wrongly here. I can’t seem to get movable light shadows to appear on translucent materials.

This is the material when it is opaque and shows the shadows supposed to appear

This is a material that is translucent but with opacity set to 1 which should have the shadows appear but it doesn’t.
I’ve tried setting to all various lighting modes on a brand new material and yet the shadowsdo not appear.

Anybody can help point out where I should check?
