[Key Values] Overwriting the wrong ones?

[Marcus101RR]

I am unable to determine how a string becomes an integer, as you can see "2147483647" and "0". When the last entry was done correctly, why are the others done incorrectly?

NOTE: I determined that when it saves a person's data, it overwrites all others. Even though their STEAMID, or BOT ID doesn't match. What is going on in this code that is causing this?

"SaveFile"
{
"BOT_Francis"
{
"Upgrades" "0"
"Disabled" "0"
"PerkBonusSlots" "0"
}
"BOT_Zoey"
{
"Upgrades" "2147483647"
"Disabled" "0"
"PerkBonusSlots" "0"
}
"BOT_Louis"
{
"Upgrades" "0"
"Disabled" "0"
"PerkBonusSlots" "0"
}
"BOT_(1)Francis"
{
"Upgrades" "2147483647"
"Disabled" "0"
"PerkBonusSlots" "0"
}
"BOT_Bill"
{
"Upgrades" "2147483647"
"Disabled" "0"
"PerkBonusSlots" "0"
}
"BOT_(1)Louis"
{
"Upgrades" "0"
"Disabled" "0"
"PerkBonusSlots" "0"
}
"STEAM_1:0:26901013"
{
"Upgrades" "00010000000001000000000100000010"
"Disabled" "00000000000000000000000000000000"
"PerkBonusSlots" "0"
}
}
