Hi @Noeldole ,
Thank you for reaching out to the Community! I’m happy to provide some assistance with this request, to ensure it gets resolved. To confirm I’m fully understanding, are referring to the third-party app Split Payment & Deposit?
If so, I’d encourage you to contact the app developer directly. This will allow them to take a closer look and ensure any left over coding is successfully removed from your theme.
To connect with the app developer, you can head into the Shopify App Store and scroll down to the ‘Built by SpurIT UAB’ section to view their support options.
Please let me know if you have any other questions or concerns.
