Hello Fillipe!

Are you using a custom form or is it something like a form container on a custom screen? the two are very different.

This is a simple concept app (copyable), that demonstrates the following techniques: Building custom forms for adding and editing list items (as an alternative to the native forms provided by Glide) Preventing duplicate new entries using [User Specific Columns](https://docs.glideapps.com/all/reference/data-editor/user-specific-columns) and [Relations](https://docs.glideapps.com/all/reference/data-editor/computed-columns/relation-column) Enforcing mandatory input items The use of visibility conditions and user specific booleans to control user flow There is nothing particula…

If I had to guess it sounds like your are using a native form with the on submit action adding a second duplicate row. Removing the on submit action would fix that.

Could we please see a screenshot of how your action(s) are configured?
