Hey when i open JEI your items are in a very confusing order! is that intended!

When i create a new world than all is fine

But can you explain how i can fix this

Not a bug. This is just how Forge assigns IDs to blocks and items. When a new world is created, it assigns them mod by mod, in the order the blocks and items are registered in each mod (in my case I register by block, stairs, slab... for each block, this is why it looks like this on your second screen). If you add a mod on an existing world, its blocks and items will just have randomly assigned IDs. This changes nothing on mod contents or stability.

so i cant do something about it that items are confused in order?
Because its so ugly to search what i can craft and what color is available

Only way is to create a new save.

This is a multiplayer server.
Is there a solution

No.
