This may be a bug in Tekkit but I am no expert in item shifting between different world types. As Oddje said, teleport tethers will work and they are a bargain at only 8 iron and 1 lapis in the middle. Try those and if you are going to tp items using enderchests, place them in the same world because I reckon they don't work when you shift items from one world to another.
