Hello @nexus_zenofn, Welcome to forums!
First, check if Epic is counting your hours correctly. To do that, go to Epic Launcher - Library and open the three dots on UEFN. There you should see something like: “You have played X amount of hours.”
Also keep in mind that just using the UEFN editor without ever launching a session may not trigger the counter.
If your hours look correct and you meet the program requirements, then it’s most likely a bug or a sync issue with UEFN.

Hope it helps!
