Having an issue with SAML access policy routing traffic

I wanted to see if anyone could possibly help me with this.  I have an access policy set up where my F5 is configured as the SP and we use an external IDP.  The IDP hosts some of the application functions and we host some others so users without knowing are navigating between the two.  On our side when the VIP with the access policy gets hit I send the application side an http redirect with the business function contained in the SAML assertion as part of the URI which is how the application knows how to route.  We're having an issue where some times if the user clicks on a tab to go to one function it'll just go back to the one it was on.  You can see it in the URL field as well.  When we check the dev tools the SAML assertion is showing up in the payload with the correct SAML variable values which should then redirect to the correct page but on the F5 I wasn't even seeing the attempt.  I'm wondering now if that may be because i don't have the Enable URL request logs enabled on the profile but can anyone help with anything they think could cause this?  It isn't always the same function where it fails and it isn't always the same amount of attempts.
