The Druidcraft crates are a static chest 27 slot size container that can combine up to a 2x2 multi-block. Toms-Storage inventory connector is somehow getting a multiplier added when reading available crate slots depending on the multi-block configuration. This multiplier is also affecting the quantities of items displayed in your UI. The inventory cable connector is also not seeing the crate multi-block. It only sees the directly adjacent crate.
