Anybody else seeing that problem, or have I misconfigured something?
I just jumped into piwik, and thought it was a kind of "hidden feature"
This is some kind of feature indeed. You can select to "flatten" the report by clicking on the arrow down below a report and then select "Make it flat" in the cog icon in the bottom right. If you are logged in, it should remember to flatten it next time.
In my opinion, it's not a solution, but just a work around to change to "flatten view".
Am I the the only one seeing that problem, or is it a general problem (= bug)?
Does it not give you valid results when using "Flatten"?
I'd understand that's a probem when using the API as one would have to set "flat=1" in the API only for this report and one would need some kind of a hack for this. However, the UI should give the same results? It's for sure possible I'm missing something.
It is both a hidden feature and a bug. See this bug report: https://github.com/piwik/piwik/issues/2956
