How to resolve labelling dashboard displaying data already labelled?

Congle

For a new project I have setup a Webapp for labelling of tabular data. I added the Webapp as a tile in a dashboard. For me both the Webapp and dashboard function properly. Yet, when I share the dashboard with a team member it displays the dataset is already labelled and does not allow for further labelling of the data. Do you have any idea how I can resolve this issue?

Thanks!
