Hextom: Bulk Product Edit

I like the concept of this app - and it seemed to function well with a few tasks.
However - i'm trying to edit some tasks by collection - and the app doesn't show my current and updated collections. They are still old ones - many of which doesn't exist in my store anymore. So I'm afraid to run any more tasks as i'm unsure of what kinds of results i may get if the app is not not connected to my current data on my store.
I'll be looking for another app ....
