There are three possible phrases that can be used in the display for “To:” (your lower image)
If there are two users are selected, one for Genealogical support, one for Technical support then two message boxes appear. One says “To: Genealogical support“, the other “To: Technical support“.
If EITHER one person is selected for both, OR, only one of the two is allocated (the other set to “none” as you have) then the simpler phrase “To: Support” is used.
