GTM Google Tag Manager: Set "page" in Virtual Page View Issue

How to track a virtual page view with GTM. Dozens of tutorials, checked them all and tried from scratch a couple of times. Issue: Page Path (aka "page") value in GA not set to what I defined in GTM.

Explanation: The page I want to track is technically one page (form.php), featuring a multi-step form. So, several html forms after each other. The end goal is that on the (successful) submit of each form a virtual pageview will be triggered. As the mechanic is based on jQuery, I plan to use a data layer push event as the trigger. Step by step:

Defined a DataLayer variable in GTM for the page path called formID and prior to the event (used as trigger) set the value, formatted as a relative path:

dataLayer.push({ 'formID':'/form-start' });
Set an event with the name formSubmit as the trigger and trigger it with:

dataLayer.push({'event': 'formSubmit'});
In the tracking ID variable as well as in the tag itself, I set the Field Name page to the data layer variable where the value of formID is stored

Testing in the console, both in the preview as well as in the published container, even after refresh, deleting cookies and much more, I get the following results:

In the DataLayer tab in the preview, I can see:

event: 'formSubmit',
formID: '/form-start'

In the Variables tab in the preview, I can see the tag fired, and for the Google Analytics settings and the Tracking ID:

fieldsToSet: [
    {fieldName: 'anonymizeIp', value: 'true'},
    {fieldName: 'page', value: '/form-start'},
    ...

However, in the Variables tab as well as in Google Analytics, Page Path is still '/form.php'.

Please, can anybody give me a hint what I am missing here? Any help very much appreciated.

Solution

So, after days, I found the issue. Still cannot explain why this is the case, but in the tag I had enabled Enable overriding settings in this tag and had enterend into the field Tracking ID below again the GA ID variable. Since I removed the variable and left the field blank, everything has been working.

Hope this is helpful to anybody who ever might experiencing same issues. Please, if anybody can explain why this is the case very happy to hear and learn.
