Grid2 Multibar's Overlap Option Missing

Hi,

Recently I’m trying to set-up my Grid2 with multibar in order to display health-deficit, heals-absorb, incoming-heal and shields.
I found a guide How to Grid2 and tried to follow its steps, yet I couldn’t find the Overlap optionin my Grid2 multibar setting.

Did the option been removed or moved somewhere else? Or there are other ways to do that?
