2-field update limitations
If you're adding information from a Research Help record to a 2-field record, such as Birth, which is composed of the Date of Birth and Birthplace fields, you cannot import a date if the birthplace field is already populated. And vice versa -- cannot add a birthplace if the date field is already populated.
There's no +Add option to import the Jul 1844 date because Ireland is already in the Birthplace field. So you must remember the new information and update it manually.
Same problem for Death and Burial fields.
I'd your algorithm to be altered to allow for an update to a 2-field record , more along the lines of the logic used when merging records. It's too easy for users to overlook updates if they are not prompted to replace/add data with the +Add prompt.
