Any changes in update_member_attribute syntax in APEX5.1 than APEX5.0?

We have developed one application using APEX5.0 and its worked without any issues. But, when we updated to apex5.1 then we are facing issues with apex_collection.UPDATE_MEMBER_ATTRIBUTE as below.

Error message -

Ajax call returned server error ORA-06550: line 3, column 4: PLS-00307: too many declarations of 'UPDATE_MEMBER_ATTRIBUTE' match this call ORA-06550: line 3, column 4: PL/SQL: Statement ignored for Execute PL/SQL Code.

Code used -

apex_collection.update_member_attribute (
                ' NEW_EMP',
                '1',
                '16',
                'ALBERT');

so when I changed above code as below its working without any issues.

apex_collection.update_member_attribute (
                p_collection_name =>'NEW_ADJUSTMENT',
                p_seq =>'1',
                p_attr_number =>'16',
                p_attr_value =>'ALBERT');

We are seeing this behavior after migrating to APEX5.1 from APEX5.0, could you please tell me is it mandatory to give parameter?

There was a bug in 5.1 documentation.
