I'd have thought you'd want either 'Date' or 'Issuance Date' replaced with your actual date (e.g. March 1, 2018), or your actual date insert after 'Date' or 'Issuance Date', not simply to have your actual date inserted after what's already in you header. What you're getting, though, is what you specified.

Any of the individual items in the header can be replaced or appended to, or even the whole header can be overwritten. You need to be clear about what your requirements are.
