Documents unusable on iPad

The Google Drive app works very well on my iPhone. When I try to use the iPad app, however, the documents are all messed up. I can find a spreadsheet and open it up but the dates listed in the lower tabs do not match the date on the document. For example: if I open up the document for schedule for February, when I click on the tab for particular day at the bottom it shows up as a completely different month. This does not happen with the iPhone app.
