Doubled cart pane with uc_i18n

When proceeding to checkout (to /cart/checkout) the page displays twice the same pane.
The first pane is cart-pane and the second one is uc_i18n_cart-pane.
Both list the items exactly the same way. Only the title is different.

Here is the HTML source of this area :

<fieldset id="cart-pane"><legend>Cart contents</legend><table class="sticky-header" style="position: fixed; top: 0px; width: 637px; left: 475px; visibility: hidden; "><thead><tr><th class="qty" style="width: 22px; ">Qty</th><th class="products" style="width: 511px; ">Products</th><th class="price" style="width: 43px; ">Price</th> </tr></thead></table><table class="cart-review sticky-enabled sticky-table">
 <thead class="tableHeader-processed"><tr><th class="qty">Qty</th><th class="products">Products</th><th class="price">Price</th> </tr></thead>
<tbody>
 <tr class="odd"><td class="qty">1×</td><td class="products">Product ABC<div class="item-list"><ul class="product-description"><li class="first">Side: Left</li>
<li class="last">Size: Medium</li>
</ul></div></td><td class="price"><span class="uc-price">600,00 $</span></td> </tr>
 <tr class="subtotal even"><td colspan="3" class="subtotal"><span id="subtotal-title">Subtotal:</span> <span class="uc-price">600,00 $</span></td> </tr>
</tbody>
</table>
</fieldset>
<fieldset id="uc_i18n_cart-pane"><legend>Your order</legend><table class="sticky-header" style="position: fixed; top: 0px; width: 637px; left: 475px; visibility: hidden; "><thead><tr><th class="qty" style="width: 22px; ">Qty</th><th class="products" style="width: 511px; ">Products</th><th class="price" style="width: 43px; ">Price</th> </tr></thead></table><table class="cart-review sticky-enabled sticky-table">
 <thead class="tableHeader-processed"><tr><th class="qty">Qty</th><th class="products">Products</th><th class="price">Price</th> </tr></thead>
<tbody>
 <tr class="odd"><td class="qty">1×</td><td class="products">Product ABC<div class="item-list"><ul class="product-description"><li class="first">Side: Left</li>
<li class="last">Size: Medium</li>
</ul></div></td><td class="price"><span class="uc-price">600,00 $</span></td> </tr>
 <tr class="subtotal even"><td colspan="3" class="subtotal"><span id="subtotal-title">Subtotal:</span> <span class="uc-price">600,00 $</span></td> </tr>
</tbody>
</table>
</fieldset>

I think the uc_i18n module adds its own fieldset without removing the original fieldset. Or somthing like this. I did not find a way to remove one of the two.

Thanks.
