Data shows up in glide data table but never in Google sheet. Is there a glide bug?

Glide page doesn't update the gsheet when I use add function

You are most likely using an Arrayformula. That makes all rows populated rows (even though they may seem to be empty) so glide will not overwrite them. What’s happening is it’s adding a new row to the sheet. Delete all of the rows that are empty. You should only have 5 visible rows in your sheet.
