Sometimes you set up accessories as a part of the bundle. This means they are being "included" into your default bundles. Their pricing is being added on that tab as well, so when you get to the Summary page the Equipment price has already taken those items into the calculation.
Example of Included Accessory price "tucking in":
The Accessories right beneath the Equipment price only show the price separately if you:
A. swapped out the 'included' ones
OR
B. included new items on the Accessories tab of building a proposal
In other words, everything that is a part of the bundle has already been plugged into the price and says "included", the rest of the accessories that have a price have been selected on the accessories page and are calculated on top of the Equipment Bundle Price.
