The item_splitter alway putout items In a ratio of 2/3 ,and keep the initial item transfer direction and distance ,even if use a wrench,put in the redstone signal, or remove the extended item_chute, Yes, even out of thin air

if I reenter the save ,that will update the item transfer direction and distance just once , and 2/3 still

forge 36.1.0 , moded just by essentials 2.11.0 and patchouli 53.1

I'm not able to reproduce this issue.
Could you send a picture of your exact setup?
Also, does breaking and replacing the splitter fix it?

Sorry , I dont know how to send pictures , So I put one picture on Dropbox : https://www.dropbox.com/s/ckvndmci9vovcmy/21716.png?dl=0

Your attachment didn't send properly, I think because you replied to the issue by email.

Thank you for your report.
This is now fixed in Essentials 2.11.1.
