Hello ! am surprise yesterday. I planed a preventive maintenance of an equipement with frequence (period field) = 90 days. And the date of next preventive maintenance suppose to be on the 22/02/2023. After some months, am very surprise that the date of the next preventive maintenance of this equipment go back to this old date which is 18/11/2022. Please someone can explan me, what can cause this ? because i think in Odoo maintenance, after input the frequence (period field) of equipement and effective date. the date of next preventive maintenance computed automatically.

Regards !
