The photo taken at HD reveals that they have pruned off several leaves that were probably split or torn. It is quite common for White Birds to develop split leaves. This is nature's adaption to the large leaves otherwise acting as wind foils and uprooting the plant outdoors. A limited amount of splitting is quite normal and not indicative of a problem necessarily.
Allowing the soil to get too dry contributes to the leaf splitting. Be sure to water copiously as soon as the surface soil is nearly dry. Keeping it close to a sunny window will also help.
