Remove colon " : " and attribute label from cart display and checkout

Hi. I am virtually pulling my hair out

I have spent a whole day just trying to do one thing. To remove the colon " : " that show on the cart and checkout page when your product has an attribute.

For example in you have a Bag product with "Color" Attributes as "blue" in your in your cart it will show on the cart page as:

Product Title => Bag
Attribute      => Color : Blue

All i have been trying to do for the past 8 hours was to find the function or the tag that output the Colon. I want my display to show as:

Product Title => Bag
Attribute      => Blue

I want to remove the attribute label "Color" and the colon " : " in the attribute output from the display in the cart and checkout page.

However, i took a look into uc_attribute.test located in example.com/sites/all/modules/ubercart/uc_attribute/test/ on line 736 , there is a code there such as

 // Cart display.
    $price = uc_currency_format($product->sell_price + $option->price);
    $edit = array('attributes[' . $attribute->aid . ']' => $option->oid);
    $this->drupalPost(NULL, $edit, 'Add to cart');
    $this->assertText($attribute->label . ': ' . $option->name, 'Attribute and selected option found in cart');
    $this->assertText($price, 'Adjusted price found in cart');

    // Checkout display.
    $this->drupalPost(NULL, array(), 'Checkout');
    $this->assertText($attribute->label . ': ' . $option->name, 'Attribute and selected option found at checkout');
    $this->assertText($price, 'Adjusted price found at checkout');
    $this->checkout();

I tried changing the line
$this->assertText($attribute->label . ': ' . $option->name, 'Attribute and selected option found in cart');

And changed it to

$this->assertText($option->name, 'Attribute and selected option found in cart');

by removing [($attribute->label . ': ' ] and save, cleared the cache and run cron but my display in cart and checkout page are still there with the colon

If i may ask, what is the use of the .test file and how can i just simply solve this issue by removing the attribute label and the semi colon. Thanks
