Website styling changes after changing the domain name

Hello,

Need help. My website looks great on default domain provided by squarespace but when i change the domain id or add another domain, It loses some of its styling. My website is https://garlic-dolphin-fkzw.squarespace.com/

I've changed my primary domain to https://reelstoryentertainment.com and now some styling appears different. Any help is highly appreciated.

That's very odd, can't image why that's happening.

I've had a look and loaded the website on both custom and built-in domains, and I can't see any change:
