Filter screen for 0MATERIAL in Analysis doesn't allow to input value directly

Hi, All!

I have a problem.

Create a query in Query designer. For 0MATERIAL I create a variable with hierarhy allow.

So, in selection screen, when I open a query in Analysis I can choose some hierarhy, or input it:

or input directly material:

And the same in opened query I can add filter to field material in the same way:

But!!! All it in DEV system.

In QUAL and in PROD on selection screen and when query is opened and I try to add filter to material field, the inputbox is gray (input not allowed):

Why?
