Description not Showing when Min / Max day not set

The description to show above the estimate does not show if Min / Max day is left blank.

Case scenario – Same Day Shipping or Pick Up

Using Max Day 1 suggest that it would be available on the next day and not immediately. Hence I chose to leave it blank and utilize the description field to indicate the time frame it will be ready “Ready in 1hr, Await Email Confirmation” or “Order by 1PM to receive today”

However, once the min / max are left blank, no description is displayed.
