How long can the data range be in ManTra report?

I downloaded the report by clicking "Export my data" from ManTra, Arlo TMS(

Here are some questions:
1. How long can the data range be? It only shows the data from 1 year ago till today.
What should do if I want a longer data period?
2. Is it possible to generate a report with desired date range defined by different users? like 1 year and 7 months ago until today.
3. I cannot find any number in any columns display "cost", but we have cost model setup on the corresponding TMS and I can see the costs on TMS, I'm not able to check and change the settings of ManTra, could you help solve it?

Thank you.
