Calendar updating time queries

Hi there,

I was updating the calendar and encountered two confusing issues:

"Bank of Off days" is not displaying the calendar year, which makes it difficult to determine which year the holidays are for.
While working with "Calendar days," I accidentally clicked somewhere on the calendar and now I can't find where it was recorded. I checked the history, but it was not there. This has put me in more effort to find where I clicked by mistake.
I kindly request you to assist me with these requirements in ProjeQtOr, or alternatively, please guide me if there is any other way to identify the issues.

Attached, please find the reference documents for your review.
