You have transplant shock. During the growing season figs do not like their roots messed with. Use a good fertile potting soil. Water in soil to remove air pockets. Make sure pot has drain holes so roots will not rot. Place plants in a shaded area. No direct intense sunlight until they recover. Some if not all of the leaves may dry and fall off or they often just recover. Leave the leaves on and you will have less shock and moisture loss. They will self prune. New leaves will eventually emerge. Accelerate new growth using fertilizer and daily watering. Figs plants with roots are hard to kill. You almost have to work at it.
One last observation. The photo shows the roots tightly encased in plastic. Roots need oxygen. When a plant is watered, gravity pulls the water downward. As the water seeps downward a vacuum is created and air is pulled to the plants roots. Oxygen is necessary at the roots to assimilate nitrogen and other nutrients. When shipping plants, before sealing, pack roots with some loose material such as damp shredded newspaper etc. and include oxygen spaces at the roots along with moist material. Hope this is helpful.
