Duplicate geometry column in geometry_columns

I have a PostgreSQL/PostGIS table with one geometry column. When I connect it to QGIS I see two of the same column:

If I make a request in PostgreSQL

SELECT * FROM geometry_columns WHERE f_table_name = 'mmune'

I can see, my view geometry_columns have two columns

I try to run function Populate_Geometry_Columns but the result is the same

SELECT Populate_Geometry_Columns('public.t_adm_commune'::regclass);

I try to redefine the column but the result is the same

ALTER TABLE mmune ALTER COLUMN geom type Geometry(Multipolygon,2) USING geom::Geometry(Multipolygon, 2);

If I question the tables pg_class and pg_attribute I see once column, that’s ok.

Have you got any idea ?

SELECT DISTINCT ST_SRID(geom) from mmune;
