Hi and welcome to the forum!
To clarify the situation for you, there are no separate Backerkit orders - all orders have been made on Indiegogo. Backerkit is just a site which is used by Philips Projection (along with many other crowdfunding campaigns) to handle all the orders they get.
If all the different numbers that are used here on the forum sound confusing, I suggest you read the following thread which should clear things up: Demystifing Numbers (Indiegogo, Backerkit etc.). In short, the numbers that are relevant are your Indiegogo contribution ID # and your Backerkit Backer ID #.
