I just noticed you can't disable the Neutral profile in version 1.5, although you should be able to.
Sorry about that, the fix for it will be included in the next release.
In the interim, if you want to disable that particular profile, please just download and open the following replacement profile by double-clicking on it.
When you double click on the downloaded file you will be asked if you want to replace the existing profile, click 'Yes'.
That's it, again sorry about the inconvenience.
