Need help on clone pool

I need to clone the server-side and client-side traffic to an application perfmon system. Most of the applications are SSL offloaded in F5 (ie., HTTPS VS), with http-to-https-redirect configured for HTTP traffic. When I perform a clone pool for both server and client side, I see unencrypted traffic on server-side data (as server already listens on HTTP), and encrypted traffic from the client-side data on the perfmon system (even though SSL offloading is performed in the HTTPS VS).

I followed https://support.f5.com/csp/article/K10379 and forwarded the application traffic from my HTTPS VS to a new HTTP VS, where I have both the clone server-side and client-side traffic enabled. The OpenText application is configured for SAML auth using an external OTDS IdP server which runs on HTTP only.

Now the issue is, when I access the application with the above setup, some part of the traffic stays in HTTP and does not gets redirected to HTTPS, and the page does not load properly.
