Don't bring over the 1949 residence that is missing a location and you should be fine attaching the census to Albert. This is a known issue that the engineers are working on.
Moved to the 1950 Census
@Howard N Camp1, are you still experiencing not being able to attach the 1950 census to one of your family members? Please let me know if you are and if so we appreciate your screenshot to be able to report it. Thank you for reaching out!
