The new "In-Game Start Time" you just entered will be displayed in the top box. Now adjust your lineup to show where your players are following the first substitution of your game (add any new players, remove departing players, etc.). The new lineup / formation will save automatically.
Repeat as many times as needed to document the lineup and formation changes in the game, making sure to press the 'Save' button for every lineup change you enter.

If you need to edit the time of a particular lineup sheet, switch to that sheet and click on the 'pencil' icon. (Don't forget to press 'Save' when finished!)
To delete a particular lineup chart, switch to that sheet, click on the 'pencil' icon, and press the 'x' button in the lower left corner of the box.

IF ONE OF YOUR ATHLETES IS WEARING ANOTHER JERSEY NUMBER IN A GAME, simply load that athlete into the 'who is playing' list as normal and click into the 'Jersey' column for the athlete. Change the entry to the new jersey number and 'close' the box. This will not only allow the player to be tagged with their new number, but all the athlete's stats for the game will track along with those already accumulated with their 'usual' / 'original' jersey number:
