If you want to return your Kiwi style settings to the original default look, you can do this using the History feature.
Kiwi saves previous versions of your settings automatically. By rolling back to the earliest version, you can restore the settings to how they were when Kiwi was first installed.
Steps to restore the original default settings
Open Kiwi Size Chart & Recommender in your Shopify admin
Go to Styles & Settings
Click History
Scroll to the oldest version in the list (this is usually from when Kiwi was first installed)
Click Rollback
Click Save
Your style settings will now be restored to the original default configuration.
Important notes
Kiwi automatically saves versions of your settings whenever changes are made.
Reinstalling the app will not reset your settings, because your configuration is saved in your store.
The History → Rollback feature is the quickest way to return to the original setup.
