Random errors in TypeScript class

I detected a very strange behaviour in WebStorm 2017.2 while editing a TypeScript file.

In a specific line an error is displayed, that does not make any sense. In line 107 it says

TS2339:Property '_' does not exist on type 'NjPropertiesBoSettings'.

But I imported lodash as

import * as _ from 'lodash';

When I now add a linebreak before that error line, the error is gone.

new line and the error wanders

Has anybody an idea what the problem here? I only got WebStorm errors, the TypeScript compiler does not mention anything.

EDIT

I found the reason. I disabled the "Use TypeScript Service" checkbox unter Settings->Languages & Frameworks->TypeScript.

Seemingly this causes the error, because I am not building a Angular2+ project.

Note

I will leave this here, in case someone runs into the same issue.
