The new Export module is simply not finished, it lacks a whole bunch of critical features. It strips all metadata and even worse the icc profile, and there's no way to include either. Why they were in such a rush to implement this premature child is a mystery.
Statements from Adobe staff (on the Adobe forum) imply that this will eventually come. In the meantime use SFW, which is now tucked away under the main Export menu. The good news is that old actions using SFW still work without modification.
