Find doesn't honor custom column names

Once I rename one of my browser columns with a custom name, FCP's Find feature doesn't recognize that new column name.

1) Rename a Custom Column "My Client's Gold" while your client is sitting there, and put the very special comments your client has to offer in that column. They will be very impressed.

2) Next session, with your client sitting there, use FCP's handy Find feature to pull up that extra special clip with your clients comments.

ACTUAL RESULT: When you invoke the Find feature, the custom name you gave the column is not available, as a choice. You have to jog your memory to try to remember, "Was that Column A or Column B that I renamed "MyClient's Gold."
EXPECTED RESULT: The FCP Find feature would include the custom name that I gave to the column, in the column drop-down menu.
