Reindexing names in Reunion

[Gerald Wright]

I have some misspelled surnames in the index, I've removed them from the People List but when I'm entering the real surname the deleted surname continues to be an option

[Dennis J. Cunniff]

You need to clear the name list (which is different from the index). As you start typing the surname you will notice the drop down list that you can choose names from. The last choice in that drop down list is "Rebuild last name list..."
Choose it.

Search for "Autocomplete Last Names" in the manual for further details.
