PowerPoint and Photoshop each have their own way of changing the opacity of an element. The most confusing aspect is that each app defines 0% transparency different.
In PowerPoint, 0% Transparency means the shape is fully opaque/solid.

In PowerPoint, 100% Transparency means the shape is fully transparent/invisible.

On the other hand, Photoshop does the exact opposite.
In PhotoShop with 0% Transparency the shape is fully transparent/invisible.
