How do I delete 'ghost' Pages documents from iCloud / iPhone?

Today I got back a brand new iPhone 4 from the repair. It was already preinstalled with iOS 5, just updated to 5.0.1 and restored data from backup on iTunes. Enabled iCloud, opened Pages and…after 5-10 seconds iCloud started to sync and I got almost dozen "ghost" files in Pages — inf folders they look like normal Pages documents, but when I open folder, they are grayed out and at the top right corner they have arrow pointing upwards. Can't delete, can't open them.

Completely closed Pages, disabled data backup in iCloud preferences, turned off iCloud sync in Pages settings. Opened Pages, chose to delete all files in Pages. Restarted iPhone, enabled iCloud data backup and enabled iCloud sync in Pages settings, opened Pages, and soon real files appeared in Pages, which I could see also in Safari browser in iCloud/Pages section. However, after one minute all those "ghost" files and folders also appeared back! I can't even drag those "ghost" documents out of "ghost" folders, can't rename, can't delete. And someone not long ago ensured us that iCloud will surely work…

I deleted Pages application form my iPhone, installed from App Store again, enabled iCloud syncing and again after 1 minute all "ghost" files are back in Pages. In Safari browser I see only one "ghost" file, all the other "ghost" files and folders are not visible at all. Any idea what to do?
