When selecting "Set recipe" on cryogenic plant Ammoniacal solution separation is selected and 50 Ammonia which appears only when "Set recipe" is selected but it is not shown as ingredients (probably from earlier crafting).
There is no ammonia in touching pipes.

Removing and setting plant again still selects Ammoniacal solution separation even though 50 Ammonia doesn't appear anymore.
Game uses several mods that don't interfere with plant.

Collab from multiple screenshots showing red and green channel before selecting set recipe.

Thanks for the report however this is not a bug. The recipe is set from the first valid signal it can find. First checking for any recipe signal it can craft, then any item signal it can craft, then any entity signal it can craft, then any fluid signal it can craft.

The Cryo plant is being set to Ammoniacal solution separation due to the presence of Ice signal on red wire.
That is coming from the requester chest just above it.
Ammoniacal solution 50 signal on red wire is coming from Cryo plant itself due to its Read ingredients.

Ah, so it was ice that triggered this recipe.
Thanks, I revised circuit logic and resetted plant.
Now it works.
