VI Module Error Post Execution

I am experiencing some troubles with a how TestStand is treating errors from a VI Module called from a Packed Library. 

 

1. I am reading some data from a serial port

2. Every now and then I read from the port and it throws an error (I am still able to read the bytes though).

3. I am clearing that specific error before exiting the VI 

4. VI Outputs the clean error cluster and the read bytes from the serial port

5. If an error occurred inside the VI, and even through the wired cluster output is w/o error, the string read from the serial port is not updating the local variable inside of TestStand. 

6. Post expressions still execute

 

Anyone have any thoughts? I have tried ignoring run-time errors already...
