property transfer steps - Reading the response and displays transferred values

I'm trying to work on property transfer functionality to  perform create /delete of the same batch 

So created a batch  and managed to extract ID  from response and saved to project properties in property transfer step ( ID shows as [38] )  When i run delete test step request it fails to read this ID as it is enclosed in tags . if i remove the tags and just say 38  delete request runs successful 

please can you let me know how we can ignore tags to be pre-populated as Property Transfer step when executed it read source JSON response  value  and put the ID value as  [[38]] in transferred values  as opposed to 38
