save and close not prompting to increase version anymore

I don't know what I did or what I may have changed, but suddenly when I make a change to something in one of my workflows (modify a line in a script item for example), when I click save a close, vRO does exactly that, saves and closes, but that's not what I want.

Previously I would always get a prompt asking if I want to increase the version of the workflow or not. How do i get that behavior back? I can't figure out what I may have done to disable it.

I'm running vRO appliance 6.0.3

Thanks
