Why do my Android 5.0 Lollipop contacts display as customize Issue?

[AC Question]

android 5.0 lollipop contacts display as customize Issue

I have Micromax Unite2 A106. I just upgraded latest version of Android 5.0 Lollipop, which is custom build version of Micromax. I am getting many issues with Latest Android 5.0 so i just want to confirm that it's with really issue with Android version or due to customized Micromax Android 5.0 version?

First, i unable to filter the contacts to display through customize opiton. There are many checkbox options of following the accounts:

-WhatsApp
--All Contacts
-Google Gmail
--MY Contacts
--Starred in Android
--Friends
--All Other Contacts
-Skype
--All Contacts
-SIM1
--All Contacts
-SIM2
--All Contacts
-Phone
--All Contacts

But i unable to checked particular option of the Account because there's unable to unchecked all except one. When i uncheck and go for uncheck another option then automatically checked all other options.

I am very frustrated with it. Please help me and please let me know that it's happening only with my handset or it's android latest 5.0 version issue/bug.

Regards,
Thanks
