Hmm... I may have spoken too soon.Upon further testing, selecting "E"
from the drop-down list returns a value of "2" as it should. However,
selecting "H" (which also corresponds with "2") bounces the option back
to "E". In other words, "H" cannot be selected or, if it is being
selected, it is being being reverted to the earliest option in the list
with the same value. This happens with all similar cases.
