Can you delete "Bob's Fluids" category and transfer recipes to, idk, "Water treatment" or "Bob's materials". Cause this tab has only 2 items in it, and that's not comfortable :\

For me this tab does not exist at all. You are probably missing a mod I use so I did not notice that. Can you send me a new save with your mods that I can easily debug this? Otherwise I probably can't move it for your setup.

The game says this is a "Bob's Metals, Chemicals and Intermediates mod" - screenshot https://dl.suyazov.com/i/2019-08-24_20-35-50.png

My mod list (TL;TR = your mod and ShinyIcons mod in list btw): https://pastebin.com/raw/exDzGEaz
Or you can download all mods from my GDrive (save included) - https://drive.google.com/drive/folders/1f9rmHGozPlf9AT1foyIiKzyoLNkaLwle?usp=sharing

I wasn't playing Factorio for a while. Is this still the case or did the issue disappear over the updates?
