scheduling Change appearance of General Scheduling Page

Hi all!

My client has a 7.0 website (1) connected with an external Acuity account.
I made a duplicate of the 7.0 website (2) because my client wanted to have a simplified version of the site in another language and with another URL. For this site I set up Acuity with the integration in Squarespace itself.

The settings of the General Scheduling Page are exactly the same for both sites, but the page looks different (the logo shows up differently and also the appointments).

Is this a common issue when you choose the integrated Acuity version in stead of the external Acuity version?
