Load Balence is not happening on pool members with two differnt service ports

Hi Team, Pleas help me and even i tried with many f5 tac support there is no fix.

1. The Vip is port 80 and backed services are 15201 and 15203 with 2 servers totally 4 Pool members.
2. We have 2 irule one is redirect with additional uri /jde/owhtml and other irule is header replace and compression and if i remove this irule its thowing this below error
3. Even i tried editing the JDEPROD irule as below mentioned but its not working as expected.

when HTTP_REQUEST { Disable STREAM processing for request (ingress) traffic STREAM::disable

 Remove the Accept-Encoding header to disable server side compression
HTTP::header remove Accept-Encoding

 Replace the incoming Host header to match what the server expects
HTTP::header replace Host "jdeprod1.corp.abc.com:15201"
HTTP::header replace Host "jdeprod1.corp.abc.com:15203"

} when HTTP_RESPONSE { if { [HTTP::header exists Location] } { If this is a redirect response, replace with HTTP::header replace Location [string map {"jdeprod1.corp.abc.com:15201" "jdeprod1.corp.abc.com"} [HTTP::header Location]] HTTP::header replace Location [string map {"jdeprod1.corp.abc.com:15203" "jdeprod1.corp.abc.com"} [HTTP::header Location]]

}
 Use a STREAM expression to remap all object references in the payload (HTML body) with the external host name
STREAM::expression {@jdeprod1.corp.abc.com:15201@jdeprod1.corp.abc.com@}
STREAM::expression {@jdeprod1.corp.abc.com:15203@jdeprod1.corp.abc.com@}
STREAM::enable

}

error screen shot:1 Connection is going to properly on 15201 is working the second connection when it goes to 15203 its throwing this error.
