Sorry I was not clear.
Let’s say I have a user with a meta key ‘user_school’ and meta value ‘Jefferson’ already present in the database: If I import that user again but the user cell under ‘user_school’ has no value, what happens is the the existing meta value of ‘Jefferson’ gets replaced with an empty value from the empty cell in the csv.
What I would like to happen is for the import to skip over the empty cell for that user in ‘user_school’ instead of replacing it with the empty value. So after re-importing the user, the ‘user_school’ value will still be ‘Jefferson’.
If I understand you correctly, the plugin is not supposed to import the empty ‘user_school’ value but instead use existing value of ‘Jefferson’. If this is the case, maybe there is something wrong with my csv format.
