First, you have set up the Option Name as a Checkbox vs a Radiobutton ...

From what I am looking at, however, you may want the checkbox as I believe you are trying to get the customer to pick 6 colors ...

If that is the case, then you should have checkboxes ...

Now, are each of the colors $9.95 or are the 6 colors $9.95?

If each color is $9.95, for $9.95 * 6 = $57.90, then you should keep the price on the Attributes ...

But if you are trying to do 6 colors for $9.95, then you should:

1 remove the prices from the Attributes

2 edit the Product and mark it as Priced by Attribute: NO

3 set the Product Price to 9.95

But, if you are trying to pick 1 color to make a 6 pack of 1 color for $9.95, then you would want to switch to Radiobutton on the Option Name ... and then do the 3 steps above ...

To force a Default select, then add another Option Value such as:
Which Color?
Default YES
Display Only YES

which forces the customer to make a real choice ...
