Airtable Interface is duplicating edits/creations/makiong changes in multiple existing Interfaces

I’m created a new Interface and when I add new groups, fields, data, etc., I see it replicated into ALL existing interfaces.

I thought Interface creations were independent from one another. Why are my existing Interfaces being updated with new data/groupings when I’m working in a new one (that was not duplicated from any existing record)?

It’s very confusing for the teams who don’t need access to all the details.

For instance, I run a real estate brokerage and my photography interface is meant to give details about the property and the SEO I want used in the videos created for the property. I have specific groups set up to quickly select which group of data needs to be seen for the objective. Now when I’m creating a new interface for buyers to see all properties, the details I put into this new interface are duplicating over to my existing photography interface and sharing new details that I don’t need the photographer to see. 

Why? This wasn’t always this way. I have several independent interfaces working well, but for some reason, in this last month, I cannot create new interfaces that don’t affect the existing ones.

I’ve tried to start multiple new interfaces to see if I’m doing something different, but they all keep duplicating the changes into the existing interfaces.
