According to what it says in the Talmud, the 3rd of the 4 Shabbatot is Parah, and the Talmud says that this 3rd Shabbat is the one immediately after Purim.

In most years this is true. However, this year, when Pesach falls on Shabbat, and in a year when Pesach falls on Sunday, the Shabbat after Purim is a "break". How / Why did this occur? Is this in contradiction of what the Talmud says?
