Reduce Operation in Structured Expressions

I'm migrating some models from 2021x to 2022x R2. We use some complex Structured Expressions that started failing which I'm trying to rebuild.

One issue is that the behaviour of the Reduce operation seems to be different. A specific use case is: I've used Map to apply a Metachain to a collection of elements to get a collection of collections. I want to intersect each of those collections.

In 2021x I could use Reduce on the collection of collections and set Intersect as the operation. In 2022x, when I select the Intersect operation, it automatically makes the Intersect a nested operation. I can't find a way to get it out of the nesting - any tips?
