Disappearing Input - Data Extract Dialog "Top" Value

I meant what I said, and I said what I meant.

Does Tableau forget what I just told it? Or does it decide that I didn't really mean it? Either way, I meant what I said, and I said what I meant, so Tableau Should remember and not make me say it again.

What I want

In this case, I'm trying to extract a percentage of the source data, and I want to pull out 10% of it, so I invoke the Extract Data dialog and enter "10" into the "Top" input area, as shown on the left in the image below. However, I want 10 percent of the data, not 10 rows, so I pull down the pulldown, as shown by the arrow pointing to the pulldown.

Tableau forgets

As shown on the right side, once "percent" is selected from the pulldown, Tableau forgets that I entered "10", and the input area is cleared.
(Or worse, Tableau decides that i didn't really want 10 percent, so it makes me enter the value I really wanted—this would be very not good and I choose not to think it's the case)

General Principle

The User should not have to repeat themself—Tableau should remember and not need to be told again.
