Read only

Every time I open a file it is set to read only and I have to save as a new version. 
It is not version related, as I am opening on the same computer. 
This is a recent develepment (I'm on 8.2.0) and is really not ideal. We save our work to the cloud and it results in having folders full of painter files, which could be just one file. Each time I make an adjustment to a coworkers file I have to resave under a different name. It's a huge space eater. What's up with that?
