Error: Inventory Management Tool

I am trying to use the Inventory Management tool with the Magic the
Gathering data files. However, I have encountered an error with the
following feature: "the capability to press a key to jump to the next
card that starts with that character."

Instead of jumping to the next card that starts with the character I
type, I jump to a card that frequently does not begin with the typed
character. For example, I might type "d" but jump to Elven Cache".

If you would like more information, please post a response and email
me directly to ensure that I receive your questions/concerns.
