Create WP Statistics report

Hi,
I would like to get a monthly report, but results are wrong or incomplete. The differentiation by provider does not work nor does the report give any numbers for sites or search engine referrals. Shortcodes for report:

Besucher <br/>
– Monat: [wpstatistics stat=visitors time=month] <br/>
— über Google: [wpstatistics stat=visitors time=month provider=google]<br/>
— über Bing: [wpstatistics stat=visitors time=month provider=bing]<br/>
<br/>
– Jahr: [wpstatistics stat=visitors time=year]<br/>
— über Google: [wpstatistics stat=visitors time=year provider=google]<br/>
— über Bing: [wpstatistics stat=visitors time=year provider=bing]<br/>
<br/>
Sitzungen <br/>
– Monat: [wpstatistics stat=visits time=month]<br/>
— über Google: [wpstatistics stat=visits time=month provider=google]<br/>
— über Bing: [wpstatistics stat=visits time=month provider=bing]<br/>
<br/>
– Jahr: [wpstatistics stat=visits time=year]<br/>
— über Google: [wpstatistics stat=visits time=year provider=google]<br/>
— über Bing: [wpstatistics stat=visits time=year provider=bing]<br/>
<br/>
Seiten<br/>
– Monat: [wpstatistics stat=pagevisits time=month] <br/>
— über Google: [wpstatistics stat=pagevisits time=month provider=google] <br/>

<br/>

— über Google: [wpstatistics stat=pagevisits time=year provider=google] <br/>
— über Bing: [wpstatistics stat=pagevisits time=year provider=bing] <br/>
<br/>
Search engine referrals<br/>
– Monat: [wpstatistics stat=searches time=month] <br/>
– Jahr: [wpstatistics stat=searches time=year] <br/>
<br/>
Search engine referrals/Google<br/>
– Monat [wpstatistics stat=searches time=month provider=google] <br/>
