Behaviour inconsistent on various webpages

[fldriessens]

Hello,

I have bought the custom skin pro and a while ago, you helped me with the display on this page (the slider): www.cougargroup.ch

However, I have exactly the same issues on other pages: Meaning, it does not display or show at all...
https://cougargroup.ch/accompagner/
https://cougargroup.ch/developper/
https://cougargroup.ch/construire/

On two pages the slider works just fine:
https://cougargroup.ch/preserver/
https://cougargroup.ch/

Could you have a look and let me know what’s wrong?

Thanking you in advance.

I did not change anything to the website since the last question.

Best,

Florence
