Great, glad to hear you got it sorted. In case anyone else with a similar problem comes across this post, this help page explains "Current Promotion" discounts:
Also, right now there's a bit of a glitch in how existing discounts are (or aren't) displayed in our Discounts Editor. If you select a Discount Name from the Current Discounts dropdown menu but don't see any specific discount details listed below that, just select All Discounts from the menu, then look for your discount in the overall list of specific discounts shown. Automatic ("Current Promotion") discounts will show a blank in the Code column of that list. We realize this may be tedious if you have a lot of discounts to look through, but this workaround should not be necessary for much longer, as our Devs are aware of the problem and working to fix it.
