Zoho Calendar Bug - auto resubscribing me to a group calendar?

I'm seeing a bug where after unsubscribing to a group calendar, clicking on my personal calendar its auto resubbing me to the group calendar after a page refresh. Happens everytime without fail.

Here is a video to demonstrate the bug:

Steps:
  1. Click on "Manage Groups"
  2. Unsubscribe from a group calendar
  3. Refresh the page
  4. Click on personal calendar
  5. Previously unsubbed calendar reappears
This only seems to happen with personal calendars. Clicking on another group calendar does not cause it to occur.
