hey guys i bought myself a TFA leader bulkhead a couple of days ago, and i have problems when i press the button for sounds..in alt mode, the siren goes off fine, and the red lights flash..when i transform him, i get the same sound and the same red light, instead of quotes and the amber lights... when i insert the headmaster unit on top, the voice changes to headmasters, and the red lights flash as it should..and then when i take it off, SOMETIMES it switches back to bulkheads voice, and amber lights, but not always.. is there light a button or something thats meant to get pushed when transforming that changes the sound, something ive missed? its not important really, im not too much into the sounds n flashy lights but i'd like to have it work like it should....thanks!
