Igneous Extruder won't take buckets

[Cosmology27]

I have a weird problem. When I place an bucket of water or lava in my igneous extruder, it doesn't take the liquid. It's not full or anything, I've never been able to get it to take liquids. I've watched tutorials on this, it's really easy, but I can't seem to make it work. I've tried changing the input/output tab a bunch, tried having RP tubes sucking items out, it just doesn't work.
Any ideas would be appreciated.

1. Hold the bucket
2. Right click the block.

^this. For whatever reason you can't add liquids to an extruder from within its interface.

wow thanks so much, worked immediately.

in the video the guy was able to put it in the gui, so maybe they updated it to this new way for some reason? either way thanks a bunch

Yeah, it definitely changed recently. Dunno why. I was confused for a while too, but right clicking with a bucket in your hand seems to be the solution.
