My REST request gets changed by SOAPUI when I transfer a value from a datasource step

Hi Guys

I have a strange issue with a test case in my suite in SOAPUI PRo 2.02. If i run a rest request individually it responses OK with not errors from Postman or ReadyAPI. When I run the whole test case which triggers that request , the request in the step gets disordered and messed up so I get 400 error  in the response.

Response of the RESt request when I run it separately

I have a test case that reads a string value from a datasource in Spreedsheet, then I pass that string into my RESt quest via property transfe using JsonPath target editor..When I run the property transfer step the value looks transfered normally.

PropertyTransfer and test to see values are read and transferred

 

The issue happens when I run the whole test case, I expect REadyAPI t to use the same request but only changing the value Im transferring from my datasource. I see that the request sets my value OK, but other values  are   disordered , duplicated abnormally.

Example:

"party_type": [
"Person",
"Person"
], Therefore that  causes my request to be like corrupted and returning parsing errors from the API I'm testing. :(

Section pARTY_DETAILS in the request gets messed up

Why is this happening? I have been working this our for 2 days with not luck.
