Google Ads Tracking and GA4 Fix

I have a client's Google Ads account that was working well with a P-Max campaign but there is some kind of error occurring in tracking, and i have been unable to fix it.

They are a kitchen retailer so they have a website with several different lead pathways, and we need all of them to track. At the moment, they have a Price estimator tool which has 9 pages for a user to complete and currently it is counting every page as a conversion rather than only the final submission page.

I haven't been able to fix this, and i'm just not sure all conversion pathways are working. GA4 is linked but also messy so i would also like audited and fixed if possible.

I need a fix asap if anyone can help please?
