Meetings module bugs

I use SuiteCrm 8.2.3.

My module “Meeting” had the compatibility mode active for the “records” but the sub-panel “Notes” did not appear. I passed the module without compatibility mode, the sub-panel is displayed correctly but the date fields which are supposed to be initialized with a certain value do not work anymore…

I have tried to repair it but without success. Do you have any idea how to solve this problem?
