Embedded sheet in dashboard - problems

HI all

I've embedded a Smartsheet sheet in a dashboard and it displays as tiles (which is what I want).  I'm the owner and there are  two other collaborators.  They have been able to open the tile and add content to the fields but now that's stopped.  They can open the tile, scroll to a field but when they start typing, they are automatically scrolled back to the date field.  The date field is not the first field and it could be blank or completed.  They are not able to edit anything either.

Both the sheet and the dashboard have been shared with them and they are both editors.  Does anyone have any suggestions?
