Different Glow Color Options for Different Imported Objects

This is a new one. I have several different Articulate Storyline projects (files). I have no idea what the folks who coded AS used as their criteria, but depending on which project I have opened, the color options for Format > Picture Effects > Glow vary greatly.

If the imported object is a "Shape", they're called "Shape Effects" and I get a nice range of glow colors to choose from - Blue, Red, Green, Purple, Teal, and Orange.

If the exact same object is imported as a "Picture", they're called "Picture Effects" and the color range isn't as spectacular - Blue, Yellow, (pale) Purple, (pale) Green, Brown(?), and Gray/Black.

In both cases, the "shape" is the same. But in one project it's a "Shape", and in another it's a "Picture". I even tried copying/pasting from the "Shape" AS file to the current "Picture" AS file; nope, it's still a "Picture" with the same less-than-desirable glow color palette.

I guess what I'm trying to figure out at the moment is how to convince AS that my object is a "Shape" so I can get my nice color options back.

Side Note: Annoying that I have to open a new session of AS just to load the other project (otherwise, the first project closes), but that's another thread.
