Coldfusion index.cfm page load firing twice and causing 404 Error - iis

Question

Trying to record "Page Loads" for custom CMS.
On page load, I invoke a CFC that saves page and user information. Works on interior pages but not Homepage.
Every "Homepage Click" records a "visit" to the homepage and then immediately records a link from the homepage to 404 Error. This means that the 404 Page is being loaded (in the background?) and firing the CFC. The verification of this is what is saved in the database. I have no idea how this is happening.
I have researched several posts here - trying varied approaches:
I have tried removing all includes - this did not fix it.
I have tried IIS Mappings - removing all rewrites and redirects - (from /index.cfm to /) - and this did not fix it.
Code as follows:`
<cfinvoke
Component="components.Page_Count"
Method="RecordPageView"
PageID="0"
Title="Homepage"
LinkName="/index.cfm"
IPAddress="#cgi.remote_addr#"
ThisUserAgent="#CGI.HTTP_USER_AGENT#"
Returnvariable="PageLinkRecorded"
