Every donation Paypal takes their cut. They take a percentage as well as a flat fee for each donation. The more the amount of a donation, the less percent they take out. So donating $5 four times is not equal to one $20 donation. So naturally you receive more because we get to keep more.

If I allowed you to receive the bonus when you didn't donate all the cash at once, it wouldn't be fair to all the others who have done it in the past and didn't get the bonus too. So I'm going to have to deny you on this one.
