Changing level of element is affecting all the other attributes of that element

Hi there,

Im trying to change the level of an element in MicroStation but all the other attributes, such as line weight, color, line style all get changed as well and I don't want that. I want the attributes to stay the same but just change only the level of the element ! Even when I don't have the other attributes check marked, the attributes still change (please see image below). I know it has to do with the symbology bylevel attributes of the level I'm changing the element onto, but on other drawings i've only changed the level and nothing else changed (which is what i wanted) even though the symbology bylevel colour i was changing onto was green.
