Single Visa Fee receipt for 3 dependendents


I have a peculiar situation.

I have paid my wife and 2 kids visa fee online and all 3 of them got the same visa fee receipt number but with 1, 2 and 3 as suffix. For example : INDY7D3R1Z8-1, INDY7D3R1Z8-2 and INDY7D3R1Z8-3 like this.

As it is its getting harder by day to get an appointment scheduled.

My question is if i process only for my wife’s application and try and get a date for her, will my kids fee be forfeited or something?

Please help.
