Template Data - Not Deleting

I recently purchased a glidegram template and I wanted to edit the data. However as I delete some data from the sheets, the changes are not reflected in the app. Please help.

Have you reloaded the editor?

Yeah. I deleted one row from the sheet in google docs and reload the editor. Once I reloaded the app, the deleted row was still there.

Could you please share that app with us and tell us which rows you deleted?
