Wrong folder created by Jasmine2 and Protractor

I've used Protractor - 4.0.11 Jasmine - 2.5.2 and conf:

onPrepare: function() {
  jasmine.getEnv().addReporter(
    new Jasmine2HtmlReporter({
      savePath: 'target/reports',
      screenshotsFolder: 'target/screenshots',
      fixedScreenshotName: true,
    })
  );}

the HTML report is created and looks like: Screenshot

The link for screenshot in html code of report:

<img src="target/screenshots/should-divide-four-and-two.png" width="100" height="100">

but the created path is: "target\reportstarget\screenshots"

I don't know why Jasmine adds the name form savePath "reports" in here. When code was:

onPrepare: function() {
  jasmine.getEnv().addReporter(
    new Jasmine2HtmlReporter({
      savePath: 'target/screenshots',
      fixedScreenshotName: true,
    })
  );}

folder path was: report - /target/screenshots screenshots - /screenshotsscreenshots

Somebody knows how to change it?
