Need to default a line item published individually as blank

Hi,

 

I have a line item with a single dimension that is being used on another grid. This line item synchronizes and displays text based on 'click' by user on the dimension in the grid. However, I want this to display as 'blank' when the user first opens the dashboard.  See below pic for reference.

The validation message published  below is the same line item. I can blank it out by using default settings as summary and setting summary as 'None'.

Can it be achieved for the above line item as well?
