I need help to reformatt this in the config file..

"Public Automatic Timed Announcements": {
"Announcement List": [
[
"Use /info for a list of rules and usable commands",
"1st Automatic Timed Announcement 2"
],
[
"2nd Automatic Timed Announcement 1",
"2nd Automatic Timed Announcement 2"
],
[
"3rd Automatic Timed Announcement 1",
"3rd Automatic Timed Announcement 2"
]
],
"Banner Color": "Grey",
"Enabled": true,
"Show Every (HH:MM:SS)": "00:00:10",
"Text Color": "Cyan"


what i want is to remove the
"1st Automatic Timed Announcement 2"
],
[
"2nd Automatic Timed Announcement 1",
"2nd Automatic Timed Announcement 2"
],
[
"3rd Automatic Timed Announcement 1",
"3rd Automatic Timed Announcement 2" 

and only show "Use /info for a list of rules and usable commands"

i cant figure out how to change it so it only does that 

"Announcement List": [
[
"Use /info for a list of rules and usable commands"
]
],
