Clicking between the "Today" button and the "This Pay Period" shortcut buttons, I think the "From" field should change to show the start of the pay period instead of staying the current date as the "To" field when selecting "This Pay Period". it would really clarify the display.
For example, selecting "today" should display both dates as 08/06/2021 (as it does now). Selecting "This pay period" should display '07/01/2021' and '08/06/2021' in the fields.
even if you manually set the from date to July 1st., clicking "This pay period" resets it to todays date
