Events count dont add up

I am sending different custom events but none of them are counting. I also can't see any of the segmentations I am adding. for example, i am collecting click events with different segmentations but I can only see the click events in the dashboard with 0 count.
I am using the web-sdk 22.6.5 & server 18.01.1

The debug logs doesnt show any errors:

[DEBUG] Sending XML HTTP request
[DEBUG] send_request_queue HTTP request completed [200][{"result":"Success"}]

The api logs shows the following error:
