We apply Bridge templates ( replace Metadata) to assets delivered by Freelance photographers. The photographers have already added there own Creator metadata. Our Template usually leaves the IPTC Creator fields untouched, by having those fields unchecked in the template. (screenshot 1)
However we now need to replace the "Creator Email" in the Metadata to reflect our contact as the Publisher. To do this I checked the Creator Email field in the Template and entered our email , other Creator fields remain unchecked (screenshot 2).
However in Bridge 2018/2019 applying this adjusted template results in all the Creator Metadata being replaced, and because the fields are blank it effectively erases the Creator Names, Address, Website etc.

That shouldn't happen. Only the Email field should be replaced. Issue?
