Adobe Reader for iPad and DropBox issues

I create folders in my DropBox account linked to my Adobe Reader on iPad app. I transfer files from my iPad into the DropBox folder through the Adobe Reader app and when I go to the folder, it contains a completely different, unrelated document. If I access the same folder on my computer, the correct file is in the folder. When I go back to the folder on the app, sometimes the correct file is there and sometimes the incorrect, unrelated file is there. Today I opened a file from a DropBox folder that waas the correct one and while I have been working on it, the title of the file I am working on changed to the incorrect, unrelated document although I am working with the correct document. I have updated DropBox and Adobe on my iPad and still have this problem. Any idea how to solve this problem?
