[ERROR] Property Transfers with "Entitize transferred value(s)"

I transferred a variable with the value "SMM-}+E49>fn:em6!BD=" to the request, but this did not pass the variable I intended ("SMM-}+E49>fn:em6!BD="), As you can see in the image.

I've already tried with "Entitize transferred value (s)" true and false, the error is the same.

Entitize transferred values - The values will have certain characters for example ampersand ("&") replaced with it's corresponding character entity value ("&")
