Dots not appearing

Hi there,

I have an issue with FF concerning the display of a dotted line in my project :

This is what I want (in the builder) :

And this is what I get in test mode (same result via Web publishing) :

For exemple, on the row "1. Throttle levers ........................ IDLE", I have this architecture :

The container containing the dots have its Expansion set to Expanded so it's responsive if I change the size of my page.

But I can't figure why it disappears when I switch to test mode or I publish to the Web...

Any help ?

(This is my first post 😄)
