Is it normale that on the "Basic Oil Processing", that we can't swap the entry and output of the fluid ?

It's normal, I just change the order of the recipes. I haven't played the new Factorio version yet, but I assume that you are reporting that there is only one exit working where it has 3 possible exit. I made a way to fill those fluid boxes, you can search for "fill fluidboxes" on settings and you can use all input/output.

That is it, I will keep play without the "fill fluidboxes".
