Path Variable in HTTPTargetConnection appended to the end

[gungorr]

Hello,

A path variable is extracted and assigned to a variable est_id succesfully. When it is used in the middle of a HTTPTargetConnection URL it is appended to the end. 

<HTTPTargetConnection>
     <URL>https://anyhost/api/Est/{est_id}/Employees</URL>
</HTTPTargetConnection>

est_id is 324324

I see this call in Postman debug session as below

<URL removed by staff> but it should be <URL removed by staff>

How can i fix that?
