Webstorm ES6 organize imports Follow

Hello,
we started using WebStorm and ES6 and I have some question about it:

1) Most annoying: why auto-import doesn't work. For example when I start typing Socket Def webstorm see it in code-completion box but when I chose it there is no entry like this

import SocketDef from '../../../src/lib/SocketDef';

WebStorm knows exaclly location beacuse I can simply jump to this code with "show source"

2) When I "Extract method" this method has wrong singature

class SocketDef {

    constructor(name, type) {
        this.name = name;
        this.type = type;
    }

}

goes to 

class SocketDef {

    constructor(name, type) {
        this.name = name;
        extracted.call(this, type); 
    }

    function extracted(type) { //should be without function keeywork
        this.type = type;
    }

}

3) Completion behaviour.

Assertions.required(empty.id);

and now I want change require funciton to 'type', after dot i press 't' and press enter, I got

Assertions.type()required(empty.id);

How can I solve this issues. Maybe there is some settings?
