can't see my sheets in DTPO 2.0

I just upgraded, and everything seems to haveimported fine, except that I have a couple of sheets which are not displaying at all. Or rather, they’re they’re there, and I can see the column headers, but the data isn’t visible. I know there’s been a lot of complex discussion about Sheets in 2.0, but these are relatively small sheets, and I just need to see the data–in any form. Any ideas?

Is it possible to export them using v1.x and to import them successfully using v2? Or could you send a small zipped example database to cgrunenberg - at - Then I could check this over here, thank you!
