Why do I have two 1PW wallets on iCloud?

I use 1PW 5 on both Macs (2) and iOS devices (2). All works fine and syncs but I noticed this this morning - Was checking on my iPad the storage in iCloud. I noticed two 1PW secure wallets are there. Don't know why.

I switched over to iCloud sync with Yosemite and was using Dropbox. So there wasn't a 1PW on the iCloud before switching to it. Can I delete one?

Because this is regarding use on both Macs and iOS - it was a toss up for me to witch thread to post. I chose here.
