EDIT: Reported to Quark repo at VazkiiMods/Quark#209

Items put into one side of double chests from Quark are being counted twice by Storage Network. Vanilla double chests and chests from Iron Chests behave as expected.

To clarify, putting an item into one side of the double chest gives me the normal result (aka, 1 item is counted as 1 item), but putting them into the other side gives a doubled count. The items are not actually duplicated when extracting them, they are simply counted twice.

did you connect 2 storage cables to the double chest? (one per block)

No, it's only one cable.

and single quark chests work well?

Just tested, and they seem to be working normally in every instance I can think to test.

Just a note, Quark dev appears to be acknowledging this as a Quark issue; my bug report has been closed as a dupe of VazkiiMods/Quark#176.
