How to remove show from Progress and Calendar?

Just add show to lists, watchlists or collection can’t notify me at the time of the update. But when i select “MARK AS WATCHED” button, it will appear in my Progress and it will notify me at the time of the update.
What do I mean by that? For example:
I add “A anime” to watch list (It doesn’t appear in Progress) and I add “B anime” to “MARK AS WATCH”(It appear in Progress). When it’s time to update the anime, Trakt only notify me B anime.
So how can I make better use of Trakt’s reminder feature so that it reminds me of the anime I want to watch. And I want to stop certain anime from reminding me to watch them.

Check your setting page. You can choose to include watchlisted items in the up next calculations.

I don’t know what you mean with reminders? But you can hide shows on your progress page or from calendar
