How to customize filter grouping in Drupal?

Question

Drupal

Good afternoon!
There is a material type with fields:
Title
Body
Text_Field = text
List_Field = list {first list item, second list item}
Date_Field
Add the following filter to Views
(Published = True AND Date_Field >= now) AND ((Text Field IS NOT NULL) OR ( List_Field = the first element of the list))
If the Eliminate duplicates checkbox is not checked in the List_Field, then only those materials that fall under the condition (List_Field = the first element of the list) are displayed.
But if you check this box, then only those materials that fall under the condition (Text Field IS NOT NULL) are displayed.
Hence the question: Why? And how all the same to display materials that fall under both conditions?

Answer 1

The problem was solved by itself, probably due to updating the PHP version.
