Storage bus can only acces 127 of an item when autocrafting

Test setup: https://i.imgur.com/COkt9Mc.png
There are 256 cobblestone in the drive on the left and 256 sticks in the chest on the right.
The terminal shows the correct amount of both (https://i.imgur.com/ZcahJvq.png) but when trying to autocraft more than 127 levers it claims to not have enough sticks. (https://i.imgur.com/TH5dIO9.png)
This happenes with anything accessed through a storage bus.

Some more info, from my testing this only occurs with blocks like Black hole storage and caches and bins. On the other hand, storage buses work fine with drawers, and me drive setups. I suspect there is an issue when it tries to pull the available amount during crafting.
