Irregular data reception

$

Hi
I have written a program to send serial values from FPGA using the ISE program in VHDL.
I want to get these values using Labview software and I have written the program below to do this.
9 bytes of fpga is sent, 3 bytes of which I have used for packing, 2 bytes for the number of samples sent from ram, and another 2 bytes for analog-to-digital converter values.

In the Labview program, I created a vi that converts the received values to DEC.

My problem is that sometimes sent bytes are correct and they are corrupt therefore the sent bytes are read irregularly in Labview.
What can I do to fix this problem?
