BACKGROUND: I believe to have found a serious bug. Either this, or there is something about Matomo reporting periods that I do not understand. At this point, I do not know which, for there is much that I do and do not understand about Matomo.
Perhaps I have exceeded a data limit of a particular set of parameter . This seems doubtful, however, as I have only been using Matomo in the way that I am using it in this case since July 10, 2018.
Please find below to HTTP GET Requests. The requests different only in the value assigned to the &period parameter. But, look at the different in output. The set of parameters returned are not the same. Notice that there are two fewer parameters when &period=year, and two additional parameters when $period=day,
