Why doesn't @import sass work when compiling with Prepros?

Question

css

Good afternoon.
The essence of the problem is that when compiling style.scss in Prepros, "@import" is not compiled.
Despite the fact that without importing everything is correctly compiled.

PS I use Prepros, because I just started to typeset not long ago and haven't learned Gulp yet.

Because of the slash at the beginning?
