How to change reagent sizes?

I have been trying to alter reagent sizes (number of cells used, not the item pictures themselves), but cannot do it.
I played around in the world/contentdb/templates/interactive/reagents file, where reagents have a "width" and "height" listed, but no matter what values I change it does not apply to in-game.

Note: I am using a modified version of Aranna legacy as well as Enchanters Half Arsed Super v1.2_New, which was the mod that already changed some reagent sizes.
I looked into the Enchanters Half Arsed file too, but that apparently just changes the world/contentdb/reagents file, whioch does not have any width or height values for reagents, so I am really stumped how that mod actually changes some of the reagents' sizes...

Am I looking at the wrong file?

Any ideas would be helpful.
