Master detail edit or add not working

I have a very simple master detail setup with shifts and employee

shifts (
  id int(11) NOT NULL AUTO_INCREMENT,
  Data date NOT NULL,
  StartHour varchar(10) CHARACTER SET utf8mb3 COLLATE utf8mb3_general_ci NOT NULL,
  Hours decimal(4, 1) NOT NULL DEFAULT 6.0,
  ServiceType int(11) NOT NULL DEFAULT 0,
  Notes text NOT NULL,
  guidx varchar(50) DEFAULT UUID(),
  `S AIB` bit(1) DEFAULT NULL,
  Confirmed bit(1) DEFAULT b'0',
  Relation text DEFAULT ' ',
  PRIMARY KEY (id)
)

EmployeeShifts (
  id int(11) NOT NULL AUTO_INCREMENT,
  IdShifts int(11) NOT NULL,
  IdEmployee int(11) NOT NULL,
  shiftmanager bit(1) DEFAULT b'0',
  driver bit(1) DEFAULT b'0',
  PRIMARY KEY (id)
)

Previusly with version 2023 and 2024 was working fine, now (after upgrading to 2025.2) I can insert EmployeeShifts only individually but from master detail, even if success message appears.

Do you have some suggestion?

What error did you get during Master/Detail add? You can enable Generate → Debug and Tools → Advanced Settings → Log to file / Log SQL to check for any error messages and the running SQLs.

Hi,
There is no error. I was already cheking logs.
when adding or editing grid child, after pressing save, I see the UPDATE on master table but no INSERT for the child record.

If you have enabled Log SQL, check the running SQL to see if there is any traces for the detail insert.

If you are a registered user, you’d better send your project file/database to the support email for quicker resolution.

I tested with the latest version, and the issue still persists.

You can open the project (project.csproj) with Visual Studio, add a break point and debug yourself.

If you are a registered user, I suppose you can still try sending your support request to the support email for checking.
