Eclipse preferences displays android tab twice

I am using eclipse neon to make an android project. When I start importing an existing project it shows me two android options.So I went to preferences of eclipse it is also showing me android tab twice. both the tabs show same path of android sdk. Here i am attaching screenshot of my preferences window. please tell me how to get the android tab only once.

enter image description here

You might have two DDMS plugins installed.
-Go to your eclipse\plugins folder
-search DDMS
-if more than one shows up, delete one of them.
-restart eclipse

I had the same issue and that is what fixed it for me.
