Tick marks in menu

Hi,

I have designed a module in storyline with menu settings as restricted and  restricted next/previous button unchecked. 

When I preview the module, the menu to the left displays  a tick everytime i access a slide and a lock for slides that aren't accessed yet( refer to the first attached file).

However, the same file, when accessed by a team member doesn't reflect the tick marks and lock in the menu (refer the second attached file).

Is there a way to fix this so that everyone who accesses the file can see the tick marks?

Thanks

Bernita
