             using (var scope = new EditorGUI.ChangeCheckScope())
             {
                 int profileID = (int)subsurfaceProfileID.floatValue;
-                profileID = EditorGUILayout.IntPopup(Styles.subsurfaceProfileText, profileID, names, values);
+
+                using (new EditorGUILayout.HorizontalScope())
+                {
