alright this is most certainly a issue of GT6inMTUtils thingy:
import mods.MTUtils.Utils;
mods.MTUtilsGT.addCustomRecipe("gt.recipe.canner", false, 128, 128, [10000], [<minecraft:cobblestone>], <liquid:soda>*500, <liquid:water>*500, [<minecraft:diamond>]);
mods.MTUtilsGT.addCustomRecipe("gt.recipe.canner", false, 128, 128, [10000], [<minecraft:cobblestone>], [<liquid:soda>*500], [<liquid:water>*500], [<minecraft:diamond>]);
results in

Scavenging the github code of theirs doesn’t help either, something is fundamentally broken
