Why are there multiple customizers on my product page?
If a customizer appears more than once on your Shopify product page, it usually means both of our theme integrations are active at the same time. You should only use one.
Check the App Embed integration
In the Shopify theme editor, click App embeds in the top bar.
See whether Customizer by Kickflip is enabled.
Check the template integration
Open your product page template.
In the template's Apps section, see whether Customizer by Kickflip has been added.
How to fix it
If the customizer appears in both places, keep the App Embed integration and remove it from the product template: open the template, find the Customizer by Kickflip block in the Apps section, and delete it. Your customizer will then appear only once.
