Error on HR dashboard when having 2 half day leaves on 1 day

Hello

on HR part, I put 0,5 leave in afternoon with a type of leaving and afterward, I put new 0,5 leave for morning for the same day with the same type of leaving.

Note that both request are in the status validated.
Something that can explain the bug : I entered the first leave in the afternoon.
Unfortunately, it does not appear on the dashboard and on the extract.

please find screenshot to explain
