If only the smallest buds at the very end of the flower stalk dried up dead, most likely it is due to not enough energy(nutrients) stored within the plant to support development of all buds. If every single bud dried and died, it is because of inappropriate fertilization after flower buds are set OR air humidity is relatively too low in Edmonton houses for your particular butterfly orchid cultivar. For your other one not developing flower buds, reasons could be either it is not mature enough or that cultivar particularly needs a low temperature stimulus (around 12.C night temperature for over 2 weeks) to initiate a flower buds development.
