Hello Sweetie!
I took another look at it, and saw that it was possible to solve this the other way around. You're right. I apologise, English isn't my first language, so I missed the importance of the word "respectively"That is because from my solution, the month Albert received is July. So Albert knows that the day which Bernard got is either 14 or 16 as both dates fall under July. But at the same time, both dates also fall under August (14) and May (16). So if Bernard has 14, he wouldn't know if it's in August or July. And if Bernard has 16 he wouldn't know if it's in May or July. So Albert can assume that Bernard doesn't know the answer.
