Delete Whatsapp backup from iCloud

Hi I want to delete the iCloud backup of my whatsapp chat history ONLY, but not the actual whatsapp application data that is stored on my mobile.

I’ve noticed when i follow these steps after disabling backup from whatsapp it says

Steps: Settings > Apple ID > iCloud > Manage Storage > WhatsApp Messenger > Delete Data

“This will delete all data for this app stored on this iPhone and in iCloud. This action can take some time...”

However i have seen a tutorial when for others it says it will only delete the iCloud backup. 

Why is it different? Ill share the screenshot from my phone and a tutorial:

If someone can help with this, it would be so great!

Is there something else enabled which is causing the delete action on my phone to delete it from phone and icloud?
