Recurring "Document Updated" Alert

When I'm using Pages on my iPad, specifically a document created from the iCloud, I continually get a message/alert saying "Document Updated". But this alert flashes three or four times in rapid succession. I touch "OK" and it flashes up again. Then again, then again. I can't write a complete sentence without getting this alert.

If I continue typing without clearing the alert, anything I type gets erased.

I'm using Pages 1.7.2 on my iPad. The latest release of Pages, that I'm still aware of, does not support mail merge which I desperately need for my buisness. Thus, I have not updated to the latest Pages platform.

Thoughts?

Thank you in advance...
