How can I remove a website from Zoho Marketing Hub Web Assistant?

Hello there, 

We have created a brand-new website and we have replaced our previous website with it. 

I started by deactivating the website and tried to add in a new one:
But unfortunately, it's telling me I can't do that. 

So next, I deleted the property - but the only option it gives now is to re-activate the website. And this simply brings back all the previous automation and statistics. 



So what I'd like to know is how can I disassociate that website and start fresh with the new website so that we can property utilise the web assistant. 

Any tips would be appreciated :)
