Navigating between pages in both Assertions Menu and review mode doesn't work

This problem is very situational : it doesn't happen every time.

Assertion menu :

Sometimes, when using the Assertions menu, it isn't possible to switch assertions pages (i.e clicking on the 2nd page of the assertions table). Nothing happens and we are still on the 1st page.

It comes from sections/pages with empty contents in EHealthSuisse database.
