That's weird, as all the other products have the knobs listed and they are all the same knobs, no matter which instrument. If you look at the Mopho page it has the same knobs the Tetra uses, even though it originally came with Evolver style knobs. The Mopho has as many dials as the Tetra and the same configuration, i.e. six encoders and five pots. Ordering the knobs for the Mopho should work, but why not drop support an email just confirming that they are actually the same caps?
