"Since then, I've had a few orders come though. When I checked my transactions there is nothing visible showing that the fee was added. I was told the fee is included in with what the buyer is charged for shipping (not visible to them) . . . ."
True: Your handing fee is added to the calculated shipping cost and that is the total shipping cost that potential buyers see.
". . . . but, there is not a dedicated field showing on my end if the additional charge was added or not on our transactions page. Can anyone give me some clarification on why the handling fees are hidden from the seller as well?"
You're right again: There is no "dedicated field" shown to the seller that states, again, the handling price they built into their Business Policies.
I don't know whether eBay has an official reason "why" the handling fees are, as you state, "hidden from the seller."
Perhaps eBay assumes that sellers who include a handling fee in their Business Policies will remember what their handling fee is?
One way to make sure your handling price was included is by doing a little subtraction after a sale is completed.
Example: on my selling ID's most recent sale, the shipping/handling price paid by my buyer was $5.96.
When I purchased postage through eBay, using calculated shipping and eBay's rates, I paid $4.57 to mail the Item to my buyer.
So, I did the math:
$5.96 minus $4.57 equals $1.39, precisely the amount of the handing fee in my Business Policy.
