[Stoneblock 4] Why isn’t my pattern provider getting any items?

The pattern provider isn't outputting any items.

• The patterns are set up properly.
• The patterns are the purple ones.
• The patterns make sure each item is sent to a different face of the chamber. I don't know if the chamber is sided.
• The chamber is receiving water from the exporter.
• There are enough channels.
• Everything here is showing as online.
• Nothing else is being crafted right now.
• There are enough material items in storage.
• I tried setting it to output to a chest instead and nothing was coming out still.
• It didn't work with non-advanced patterns and pattern provider either.
