Matomo not tracking all pageviews and goals

Hi there…

I’ve detected that Matomo isn’t tracking all pageviews and goals. There are no errors in the developer console or such like. It seems that Matomo is tracking randomly. I refreshed a site 10 times each 10 seconds, Matomo shows only 4 pageviews.

Another thing that i’ve recognized the past few days:

There is a undefined JSON/CSV-String in my Reports: “email”,“xsid”,“FOO”
