Why does WebStrom underline the loop in Jade?

Question

HTML

- for (var i = 1; i < 7; ++i) {
      .col-md-2.licenses-item
          .licenses-item--logo: img.licenses-item--logo--image(src='/img/index/client_1.png')
          .licenses-item--desc Лицензия
      - }

The brackets {} are underlined in red, but the code is generated without errors. Writes missing }

Answer 1

Apparently because it is configured to work only by nesting through tabulation, something like this:

for (var i = 1; i < 7; ++i)
      .col-md-2.licenses-item
          .licenses-item--logo: img.licenses-item--logo--image(src='/img/index/client_1.png')
          .licenses-item--desc Лицензия
