InDesign: Automatically Beveling shapes

Hello,

I'm working on a document previously created by someone else and I've noticed that I can't create shapes without a bevel/shading being added. I've checked the 'fx' tab and there isn't anything checked for this and when I do select the 'Bevel and Emboss' tab, it adds another onto the existing one.

If anyone knows a way to turn this off and stop it automatically adding this effect, that would be great.

Thanks!
