It appears that your tool is identifying the same user as four distinct users. This is occurring despite the fact that the user is utilizing the same browser, IP address, and continuing within the same session without closing any windows. The only variable is the "source" value. It is perplexing that the system categorizes a visitor as entirely new based solely on a different source. This approach implies that any changes in the user's entry point to our site result in starting their history afresh. Consequently, if they interact with any email marketing, non-Google/direct traffic, Google, Bing, or other advertisements, they are recorded as "new" users, devoid of any prior history, even if they are still within the same session and just minutes apart.
