Videocon Industries — basic service tier pack show channel is mandatory channel

Address:

Gandhinagar, Gujarat, 382308

I am trying to remove non dd channel from basic service tier pack but not show any option to remove and all 100 channel is show as mandatory channel.

After we will choose more than 25 channel then they say "₹20 + taxes if no. Of channels is more than 15 and ₹1 per channel + taxes for 15 or less channels".

Why videocon d2h add all 100 channels is mandatory channels which is some non dd channels?
