EditorGUILayout is cutting off my Toggle label

I'm creating a toggle button with 'EditorGUILayout.Toggle("25 character string here", myBooleanValue);' . Unfortunately, my 25 character string is getting cut off, so all you can see is 'string here'. Which is really weird, because there's plenty of room in the inspector(take a look at the screenshot). I've tried passing in GUILayout.Width(Screen.width) and GUILayout.ExpandWidth(true), but neither of these seem to have any effect. What's happening here? (It seems as though I'm just making some stupid mistake, since I haven't been able to find this question anywhere else)

Could you paste the code you're using?

Maybe try using EditorGUI.Toggle and pass it a desired Rectangle - it's much easier to control sometimes
