After much "trial & error" I have found that the PLUGIN: "Pay With A Like" does not play well with Gravity Forms (conditional logic).
All other "normal" forms work functionally with the "Pay With A Like" plugin, but it wipes out the "conditional logic" forms (i.e. they don't show up on the page at all).
I even tested by "changing theme to basic TwentyFifteen, etc" - but it was only affected with the PLUGIN: "Pay With A Like" was activated.
I would love to use this plugin in the future... but for now my "ORDER FORM" is affected (not good for business SO, the question is... can this be fixed? Is there a workaround? Will I ever be able to eat just one BBQ Pringle?
These and many more questions vex me.
Thanks for the future solution!
