When reading data from UART, fetching data is not correct

Question

I am sending data from Xbee 3 pro (router) connected to Teensy 4.0 microcontroller, to another Xbee 3 pro (coordinator). I am successfully getting data,but the data i am getting is not structured correctly as lines. Lines are mostly combined.

printed data:

1.00,4096.00
,-0.21,-161,-0.79,1.03,23.13,1020.02,-0.21,-16.52,0,0,0,0,0.00,0.00,0.90,0.00,131.00,4096.00

Getting data from C++ program:

void readTelemetryData(){


    data.telemetry_conn_port = serial_t_port;

    serial_t.open(serial_t_port); 

    if (!serial_t.is_open()){
        data.telemetry_conn_status = "N/A";

    } else{
        
        serial_t.ignore();
        getline(serial_t,incoming_data);
        data.telemetry_conn_status = "SUCCESS";
        if (incoming_data.find(',') != std::string::npos){
            
            data_seperated_t = split_data(incoming_data, ',');

            data.time = data_seperated_t[0];
            data.Accel_X = data_seperated_t[1];
            data.Accel_Y = data_seperated_t[2];
            data.Accel_Z = data_seperated_t[3];
            data.Gyro_X_Raw = data_seperated_t[4];
            data.Gyro_Y_Raw = data_seperated_t[5];
            data.Gyro_Z_Raw = data_seperated_t[6];
            data.Gyro_Yaw = data_seperated_t[7];
            data.Gyro_Roll = data_seperated_t[8];
            data.Gyro_Pitch = data_seperated_t[9];
            data.Baro_Temp = data_seperated_t[10];
            data.Baro_Pressure = data_seperated_t[11];
            data.Baro_Altitude = data_seperated_t[12];
            data.Baro_Altitude_Error = data_seperated_t[13];
            data.ParachuteOn = data_seperated_t[14];
            data.LegsDeployed = data_seperated_t[15];

            data.Voltage = data_seperated_t[19];
            data.Kal_X_Pos = data_seperated_t[20];
            data.Kal_X_PosP = data_seperated_t[21];
            data.Gyro_Sens = data_seperated_t[22];
            data.Acc_Sens = data_seperated_t[23];
            

        } else {

            data.message.push_back(incoming_data) ;
        }

        
        
    serial_t.close();
