Structured data items are invalid

Hello, 

I keen getting this error 4 items detected: Some are invalid. When I crawl my site on Google Rich Results Test. 

I've tried adding schema mark up in the header & body. I've also tried adding the business details via the 'Settings' 'Selling' 'Business information' tab on Squarespace. 

From what I can see there is possibly an incomplete schema injected somewhere in the site, how do I find this and delete or amend it? 

Any help or guidance would be greatly appreciated.
