Nicholas - Hi again!
No, they (Noland-19 and Noland-216) don't need to be merged...they're totally different. That's what was so weird about the Noland-19 showing up in biography area. If I understood correctly, Noland-216 was assigned a temporary ID (I assumed Noland-19) while the gedcom was being processed, which should have been merged into the actual ID (Noland-216) once your gedcom was added to WikiTree. The temporary ID staying in the final profile (albeit only in the text of the automatically generated source paragraph) is a glitch.
