April 2018 Contradiction

Hi, There seems to be a contradiction in the Calendar for 2018.  In the Calendar View for 7th April 2018, it shows the Torah Portion is Shmini, but when I click on it for more details, it says Shmini is read on 14th April.  I get the same for the 14th when clicking on Tazria-Metzora, it says it is read on 21st April.  I am looking for the Israel readings and believe this is something to do with the difference between Diaspora and Israel reading schedule.

Could you please clarify?

Many thanks!
