Phpstorm doesn't compile main sass file after changing import files. How to win?

Question

phpstorm

there are two identical projects, the file structure is the same.


So, in one project, after changing the imported files, such as "_header.scss", the main file "style.scss" is recompiled itself. And in another project, you have to make changes to the main "style.scss" file itself in order to start compilation.
structure of the main file:

file watcher settings are the same:


How can I make the compilation start after changing the imported files?

Please, help!
