The select time range does not include the entire bucket it may contain partial data

I want the graph to show just one day, and it shows me 2 days, with this message "The select time range does not include the entire bucket it may contain partial data".
In attached I will send you the graph and the advance settings that I did.
This happens when I choose the option "Journée entière" created by me.

It's the same thing as "Today" or "Yesterday", but in this time ranges work, but for the one I created it dosen't work.
The graphics each line it's the count of records with timeshift from 1d 2d 3d 4d 5d and 1M(Month).

I know I can take the grey day clicking in the drop partial buckets, but this it's not the solution for me.

Why does this happens only for this field that I created?
