IntelliJ keeps adding duplicate Copyright Template Headers to Java Source files

Question

IntelliJ adds too many copy right headers

I setup IntelliJ to include a licence into source code as a comment into the header. For some reason IntelliJ repeated the copy right statement for several in all files.

So currently all files have between one and five (or more) repetitions of the licence header, e.g.:

/*
 * Copyright [2014] [John Doe]
 *
 *    Licensed under the Apache License, Version 2.0 (the "License");
 *    you may not use this file except in compliance with the License.

 */

How can I remove multiple repetitions of the same header?

I could not find a fuction to remove the headers again. Does IntelliJ provide such a functionality? Should I use Linux board tools and replace tne string? How can I do this safely?

According to Creating Copyright Profiles - IntelliJ IDEA 13.1.0 Web Help (the bold font is mine):

In the Keyword to detect copyright in comments text box, type a character string to distinguish copyright notices from other comments during copyright update.

I.e. it needs to be a single substring unique enough to reliably identify your copyright notice specified in the copyright profile.
