Marketpress on multisite - orders being seen by other sites/users in network!

Hi,
this is quite a biggy! It seems that when orders are placed in my marketpress multisite network they are showing up as orders on other users' dashboards as well. I've just placed a sandbox order on one of my test stores, logged in as network admin and logged at some other users' dashboards and I can see the order on a bunch of them. I don't even know where to begin troubleshooting this! Everything is 100% updated.

This is a showstopper! Has anyone seen this before??
