This can happen sometimes, but it might be that they are getting too much light. You can try moving them into a little more shade, and they should stretch out. This is no problem though. It is actually healthy. Here is an article for more information on the plant: https://www.gardeningknowhow.com/ornamental/flowers/clivia/clivia-plant.htm
