The bottom photo shows everything I got with my twin DI set up. The second photo shows the whole plastic bit having come out of other bit. How do I glue it back in? And in this photo there is a foam thing a couple of centremetres in. Do you not push white bit in any further than that? The top photo show that one plastic bit is longer than other one. The longer one doesn't allow to put whole thing into DI; it's too long and the screw bit won't go on, do I cut it shorter?
