It sounds like she may have been startled or frightened once when she was eating canned food and now relates the scare to the food.
At this point I would feed the cats separately and give her the dry food she wants for about a week to settle her down. Once she is consistently eating the dry at feeding times you can add a small amount of canned to the dry and see how she reacts. If she accepts the addition give it a few days and then add a bit more canned to dry and so on until you have her back on the canned.
With cats slow and steady is the best route to go. Also don't leave food out all the time have set feeding times, put the food out at those times and for a set period of time(like 20 minutes) and then remove the food. Three times a day for kittens is good.
