i2c reading extra byte

I'm new to this so I may have done something stupid. When I run my code, the msp430 (master) does an extra byte read instead of sending the stop code. I'm attaching the logic analyzer. Thanks!

code (I bolded the parts I thought relevant):

#include <msp430.h>
#include "gy-80_config.h"

int RXByteCtr, RPT_Flag = 0; // enables repeated start when 1
volatile unsigned char RxBuffer[128]; // Allocate 128 byte of RAM
unsigned char TxData; // TX data
unsigned char *PRxData; // Pointer to RX data
unsigned char TXByteCtr, RX = 0;

void Setup_TX(unsigned char );
void Setup_RX(unsigned char );

int main(void) {
WDTCTL = WDTPW | WDTHOLD; // Stop watchdog timer

P1SEL |= BIT6 + BIT7; // Assign I2C pins to USCI_B0
P1SEL2|= BIT6 + BIT7; // Assign I2C pins to USCI_B0

while(1){
//Transmit process
Setup_TX(ACCE_ADDR);
TXByteCtr = 1;
TxData = ACCE_DEVID;
while (UCB0CTL1 & UCTXSTP); // Ensure stop condition got sent
UCB0CTL1 |= UCTR + UCTXSTT; // I2C TX, start condition
__bis_SR_register(CPUOFF + GIE); // Enter LPM0 w/ interrupts
while (UCB0CTL1 & UCTXSTP); // Ensure stop condition got sent

//Receive process
Setup_RX(ACCE_ADDR);
PRxData = (unsigned char *)RxBuffer; // Start of RX buffer
RXByteCtr = 1; // Load RX byte counter
while (UCB0CTL1 & UCTXSTP); // Ensure stop condition got sent
UCB0CTL1 |= UCTXSTT; // I2C start condition
__bis_SR_register(CPUOFF + GIE); // Enter LPM0 w/ interrupts
while (UCB0CTL1 & UCTXSTP); // Ensure stop condition got sent
}
}

// The USCI_B0 data ISR is used to move received data from the I2C slave

}

}
}
