This is due to the mechanism of Samsung SmartThings itself. When a user binds a SmartThings account for the first time, the information is synchronized to SmartThings. After the user modifies the information in the Meross APP, SmartThings prevents Meross from sending the updated information. This is not a malfunction of Meross itself, but a strategy of SmartThings. Similarly, if the user modifies the device name in SmartThings, it will not be synchronized to the Meross APP.
