Disappearing UU matter?

[Kakoka]

Hi there. I've noticed a strange bug with the export bus and autocrafting table, and was wondering if anyone has run into this as well.

I have a small AE network importing UU matter from a mass fabricator and exporting it to a basic autocrafting table to turn into copper dust. I've noticed that when the export bus is set to export stacks, it will take a stack of UU to replace 3 used UU and throw the rest of the stack away. This results with thousands of UU being deleted and never used.

This problem also occurs with other stackable items, such as scrap.

 

Any thoughts or ideas on what's going on and how to fix it?
