Crinkled leaves are an indicator that the plant received insufficient water while the new leaves were developing. This can be caused by either loss of roots due to keeping the growing media too wet, which has killed most of the roots, or by simply not enough water to an otherwise healthy root system. Miltonias prefer to have their roots constantly damp, but never soggy. Older growing media will tend to hold water for longer periods of time so be careful not to overwater. Miltonias also prefer lots of humidity, with 50-75% being the ideal amount. Light, morning misting of the foliage is helpful in hot, dry conditions but be sure to keep standing water out of the leaves or soft rot may develop, especially if there is poor air circulation around your plants.
