Notion filters work unstable on emtpy strings

Describe the problem/error/question

I tested Notion Get Many filter on empty strings. I wanted that if there’s an empty field in the form, then it is nothing to look for in Notion.

What I expect

no returned items at all

What actually happens

It returns all the items

What is the error message (if any)?
