Some product price options not showing in product view: how to show them all?

[SteP[IT]]

I'm back to the product price question (already discussed in a previous tread but still pending, in my opinion....) for a further clarification request.
I'm testing the 3.0.3 release on J 2.5.28, but I can't get all the price options displayed: also cheking the whole set of option inside the price backend tab (refer to the left side of the attached pic) some prices option still lack (on the right of the same pic).
In attached picture you can see the result I get for a product  (having a base price, and discount & tax rules applied): option numbered 1, 2 & 3 are missing (is this correct?), this is caused by my setup (and if yes, why?) or there is something else that lead to this display mode?
Can please someone tell me were is my fault, if any?
Thank you in adavance

This is what I see using 3.0.3 default products and VM templates with VMBeez Joomla template. All price options are selected in configuration, a 5% discount applied before tax and then a 20% VAT rate applied.

Yes, I saw that, thanks... but I would like to understand why I can't display the remaining 3 options values (only labels are displayed) I see in my test site!!
I'm using a non-standard Joomla template (yootheme nano3) but the VM template is the standard one, no modding... sould they be visible or not? they could be useful for me....
