Vert phantom shares

I seem to have a bit of an issue with Vert.

Last night before I went to bed, my Vert Shares were at 37.39M, this morning they are at 41.72M.

Sounds pretty normal right? But, I stopped mining Vert after the last payout a few days ago as I switched to mining Mona.

It doesn't look like I'm getting paid for my phantom shares at least, so I'm not pinching off of other people's work, so maybe just a display issue? :)

Thanks

Ben
