Over populated where clause on leftjoin

Where $invoiceNum = 10

    list($transactionRecords, $transactionMetaData) = getRecords(array(
        'tableName'     => 'member_transactions',
        "where"         => "member_transactions.num = $invoiceNum",
        'leftJoin'      => array('members' => 'member_num'),
        'limit'         => 1,
        "debugSql"      => true,
    ));

Is generating the following SQL and error:

#(added all the columns from both table and their actual values to the where clause)

ORDER BY membership_year DESC,member_num LIMIT 1

MySQL Error: Column 'createdByUserNum' in where clause is ambiguous

I am using the membership addon (with its own account table called members). I  use similar code in another area but the where clause does not add all the columns from both tables. I do not see why the where clause is being over populated.

Anyone have any ideas what is going on here?
