mysql – Phpmyadmin : one to one relationship

I carried out EER diagram in MySQL workbench including different relationships: one to one, one to many, zero or one to one, zero or one to zero or one, and one to zero or many.

However, when I apply the model to phpmyadmin using “Forward engineer”, all the relationships are converted to one to many, and I do not the reason and how to implement my original relationships?

UPDATE:
The relation between equipment and inspection is one to one, but it appears in phpmyadmin as one to many.

CREATE TABLE IF NOT EXISTS `equipment` (
  `S_N` int(10) UNSIGNED NOT NULL ,
  `Equipment_Description` varchar(45) NOT NULL,
  `P_N` varchar(45) NOT NULL ,
  `OrderNo` int(10) UNSIGNED NOT NULL,
  `V_N` int(10) UNSIGNED NOT NULL,
  `LS_N` int(10) UNSIGNED NOT NULL,
  PRIMARY KEY (`S_N`),
  UNIQUE KEY `S_N` (`S_N`),
  KEY `OrderNo_idx` (`OrderNo`) USING BTREE
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

CREATE TABLE IF NOT EXISTS `inspection` (
  `Inspection_ID` int(10) UNSIGNED NOT NULL AUTO_INCREMENT,
  `FK_INS_S_N` int(10) UNSIGNED NOT NULL,
  `Notification_No` int(10) UNSIGNED NOT NULL,
  `Notification_Status` char(2) NOT NULL,
  `Number_of_Defects` int(10) UNSIGNED NOT NULL,
  `INS_Plant` varchar(25) NOT NULL,
  `INS_Location` varchar(30) NOT NULL,
  `INS_Work_Date_start` date NOT NULL,
  `INS_Work_Time_start` time NOT NULL,
  `INS_Work_Date_finish` date NOT NULL,
  `INS_Work_Time_finish` time NOT NULL,
  `INS_Actual_Duration` time NOT NULL,
  `INS_Forecast duration` time NOT NULL,
  `WBS` varchar(45) NOT NULL,
  PRIMARY KEY (`Inspection_ID`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8;

Thanks in advance.
