SOAPUI PRO How to transfer the latest value in Rest API response

Tanya,

Awesome sharing..

but am facing some issue like

if am passing the below syntax in Property transfer am able to get the last value

$[1]..versionNumber[-1:].versionNumber

but below the versionNumber property transfer value has open and close brackets like []
[0000-000-000-0000-0000000000000]

if am passing the same property value in my API request query parameter, it's passing with open and close brackets []

issue is need to pass the value without open and close brackets []

It's possible, please guide me if am wrong anywhere...
