When saving a review with multiple axes, the first axe values override the other axes' values

Use the default Drupal theme.
Create a review node type with 2 axes : axe1 and axe2, which are applied to nodes of a custom type "Hotel".
Create a review and fill in data for both axes (score and review text).
Edit the review again.
Expected result : we see the data filled in for both axes when the review was created.
Real result ; the score and review text for axe1 are ok. Score and review text for axe2 are overriden by axe1 values.
