Hello, I'm using data mesh to bring information from other sheet(projects in this case) I have them linked with a column named "helper"

I noticed that new data is not being added, however existing information is updated once a change is made in the source sheet.

if I select copy and add data it adds duplicates at the end of the sheet. I'm not sure how to setup this in order to get accurate data and updates

I'm using the helper column because some projects don't have project numbers assigned therefore the data is not being linked until a number is assigned but we want to have visibility of the project even if no proj number is written in the source sheet corresponding field

Thank you for your help!
