Apologies something went haywire with the Laverna's Ring and D24/D30 if you selected them as Add-ons during the campaign.   

I went through all the Backerkit guides and thought I had those items set up properly to just ask which color you wanted when they did the pledge manager.

But for some reason its making you buy it twice (the first one with no color and the 2nd with the color you picked).   I have already messaged Backerkit and they messaged back asking for some more information to see specific backers being effected so they can solve it.  (It at least made me feel better that they looked at my add-on and thought I did it right as well on first glance).

So BackerKit is on it .    That said ... I did have a way to fix it as a creator that might work for you if you want to get your pledge manager finished.

If you delete the add-on you made during the project and then you add it back from the add-ons section of the pledge manager where the add-on items are already a specific color (not a choice) ... that should solve your problem.    If you do not have the option to delete add-ons made during the campaign ... no worries (that just means its a creator superpower) and Backerkit promises they will figure out the issue soon.
