All of my managed "Simple XML file"s are appearing also in "Ivy configuration" files

Steps to reproduce:
1) Jenkins -> Manage Jenkins -> Managed Files
2) Click Add a new Config
3) Choose Simple XML File and click "Submit" and then "Submit" again
Notice that the XML config that was just created only appears in "Simple XML file"
4) Restart Jenkins, after navigate back to Managed Files
You should see XmlConfig Duplicated in "Ivy Configurations" now.

5) Delete the Duplicate entry from Ivy Configuration
You should see the screen refresh, the item in 'Simple File Xml' has been deleted, and the item in 'Ivy Configuration' still remains

I'm not sure if Ivy Plugin is related here, but am assuming the 'Ivy Configuration' option is only available due to that plugin being installed, based on the information included in https://wiki.jenkins-ci.org/display/JENKINS/Config+File+Provider+Plugin
