Garry ACN will have asked for your current comp for a variety of reasons, none of which are obscure - to evaluate you against your level of experience/peer group etc, to establish whether they have the budget to hire you at a given level, and for internal benchmarking so they can compile comp information when they are looking at what they need to pay. Quoting a full comp rather than base is quite commonplace, so as the others have reassured you, no need to worry. If you are challenged about the discrepancy - which I think would be very very unusual - blame the recruiter who made your application.
