TSConfig.json in root folder in a TypeScript project

In my TypeScript project in WebStorm I have a src folder with my *.TS files.

Project Folder
-- src Folder
---- core Folder
------ myCore.ts

I added a tsconfig.json to the root folder and "Enabling TypeScript Compiler" with "Use tsconfig.json" the compiler sees this file as a TS file and I'm getting errors.

If I change the Settings to "Set Options Manually", the compiler works but it generates tsconfig.json.js and tsconfig.json.js.map.

I fixed moving tsconfig.json to each TS Folder.

I think that Compiler must ignore the tsconfig on the root.

Thanks
