While in Your Funding History there will be correct entries? On the other hand, if you offered your dollars at a lower interest and there are bids which are higher than that (i.e. people want to pay more than you ask), why would you get higher rate and not those people lower interest (i.e. your rate). This is a tricky question, and it might not work in the same way as regular trading orderbooks work. It might be a bug or an intended feature
A lending bid or offer first tries to execute against existing bids/offers in the order book and any portion that is unable to get filled will be placed in the orderbook. I don't think this is a particularly controversial procedure, and am unaware of any kind of market place that does not execute orders this way
This is how it should work
But as the guy above says this is (was) not the case. As I got it from his post, he complains that offers are executed, first, out of the queue order, and, second, not at the interest rate as they should. Indeed, this shouldn't be controversial but I had seen a similar bug or behavior at Cryptsy (with regular orderbooks, obviously) when only some part of my order got filled, and then another order placed later at the same price got executed, and it was controversial, to say the least of it
