Does not work Sort paragraphs alphabetically

Hello, friends!
I have Windows 10.
“Sort paragraphs alphabetically” in the “Materials section” does not work in my Scrivener.
This option is not activated, it is always light grey . How to activate this option?
Thank you in advance for your advice!

I’m not sure what you mean by “Materials section”, but if you’re referring to the Edit > Sort Paragraphs > Ascending/Descending command, then you need to make sure you have the relevant text selected (highlighted with the cursor) before the option will become available. The selection also needs to contain more than one paragraph.
