You have to save players timer id and kill it if they got a damage before the callback of remove get called

PHP код:

new PDamageTimer[MAX_PLAYERS];
public OnPlayerTakeDamage(playerid, issuerid, Float:amount, weaponid, bodypart)
{
    new gString[128];
    format(gString, sizeof gString, "{ff0000}-%.0f",amount);
    if(_:PlayerDamage[playerid] != -1)
    {
        Delete3DTextLabel(PlayerDamage[playerid]);
        PlayerDamage[playerid] = Text3D:-1;
        KillTimer(PDamageTimer[playerid]);
    }
    PlayerDamage[playerid] = Create3DTextLabel(gString, 0xFFFFFFFF, 0.0, 0.0, 0.0, 7.5, -1);
    Attach3DTextLabelToPlayer(PlayerDamage[playerid], playerid, 0.0, 0.0, 0.4);
    PDamageTimer[playerid] = SetTimerEx("RemoveDamageLabel", 3000, false, "d", playerid);
    return 1;
}
forward RemoveDamageLabel(playerid);
public RemoveDamageLabel(playerid)
{
    Delete3DTextLabel(PlayerDamage[playerid]);
    PlayerDamage[playerid] = Text3D:-1;
    return 1;
} 


also be sure to do that on player connect

PHP код:

PlayerDamage[playerid] = Text3D:-1;
