Remove activity (delete) - bug in fw

Hi, I have a problem with remove activity which I created. I found this help:

  1. From the watch face, hold MENU.
  2. Select Settings > Activities & Apps.
  3. Select an activity.
  4. Select an option:
    • To remove an activity from your list of favorites, select Remove from Favorites.

    • To delete the activity from the apps list, select Remove.

If I want to delete activity from the apps list I select Remove but activity still stay at app list :-(

Activity can only be removed from the favorites list. In the list where activities are created / copied / choose I don't know how to delete them.

Some idea? THX
