Hi shahyads,
It would be our pleasure to answer your questions.
The icon in front of your highlighted selections indicate content that was on your device when the backup was created, but subsequently deleted. The "Reduce the size of your iCloud backup" section of this article outlines the steps you may have to take to remove that content from your iCloud backup.

Choose which apps to back up on your iPhone, iPad, or iPod touch
1. Go to Settings > [your name] > iCloud.
2. Tap Manage Account Storage or tap Manage Storage, then tap Backups.
3. Tap the name of the device that you're using.
4. Turn off any apps that you don't want to back up.
5. Choose Turn Off & Delete.
The next time your iPhone creates a backup, anything you elected to turn off will be removed from the backup.
