Calendar skipping entries to delelte

I am composing the new document and sending the invitation to user and user have accepted itThis invitation get rescheduled and went to user, and there was no action from the user (idle on calendar as ghost entry).

Another reschedule appear and went to user, and again there was no action from the user (idle on calendar as ghost entry).

A “CANCEL” went to user for this invitation and user acted on it, and now only the cancel and the first entry which user has acted being deleted and the ghost entries are staying on the user’s calendar.

Sequence number went up along with updateseq number, but both of them are same increment.
