Date and time field in record page - strange behavior

Hi,
I have a module with a “date and time” field and I use a record page to add values to this module.

Although the “date and time” field is empty, at the record page level, after pressing the save button , information related to this field arrives in the database.

Steps to reproduce the issue:
Step 1 → fill the “date and time” field with a specific value
Step 2 → clear/remove information from “date and time” field (value added in the previous step).
Date and time field looks empty (empty date + empty time).
Step 3 → push save button.

inside the database will be inserted the value set initially (Step 1), although when I push save button the date and time field was empty.
