Count number in category extension differents from number of posts

Dear support team,

I've configured my Joomla website to display the category extension with a number of items to display that could be up to 1000.

Furthermore, my total number of posts is 79.

But, when I sum the counts displayed in each category (in the category extension) I get a total 1+3+9+29+6+13+4 = 65 posts whereas it should 79.
And I don't understand why the number of items is different

Two more things:
- all my posts are published
- My is a multilingual site (En/Fr) and all my posts are set to All

Could you help me ?

Joomla: 3.3.6
Easyblog: 3.9.19335

Regards,

Cynthia
