Session Policies don't seem to be working as Idle Sessions stay connected

Hello.  I have set Citrix policies within Citrix Studio in my XenApp 7.15.  I am finding the session's are not disconnecting/clearing and are staying connected for over 12 hours, basically until I actually close the session though I have the following set.  These are published applications, not published Desktops.


These settings are part of the Unfiltered default policy which is applied all objects in the site.

Is there a better practice for policies in XenApp 7.15 without using AD GPO's?  Are there other settings I am not finding that would handle this communication?  

I am looking at the following articles for reference,
https://support.citrix.com/article/CTX216719
https://docs.citrix.com/en-us/xenapp-and-xendesktop/7-15-ltsr/policies/policies-default-settings.html

Any thoughts are appreciated.
