Delete Auto-generated kwrds "_%"(0x5F 0x25) makes all User-defined kwrds disappear

Delete Auto-generated keywords "_%"(0x5F 0x25) makes all User-defined keywords disappeared

PLEASE MAKE A COPY OF YOUR FILE BEFORE YOU VERIFY THE CASE.

How did it happen?
I linked a .uue(uuencode) text file into my .urd file for reminding purpose.
Then I found it generated more than 800 "Auto-generated keywords" and decided to delete all of them.
All my User-defined keywords disappeared after I had deleted "Auto-generated keywords"
I made some tests and filtered out irrelavant items, "_%"(0x5F 0x25) came forward.

The disappeared User-defined keywords should be still somewhere because all the checked items are intact when you re-create them.
I am not sure if it has something to do with the Traditional Chinese environment or it is a bug.
Please beware of the character pair "_%" (0x5F 0x25) if you have lots of User-defined keywords.(It kills you to think of all the keywords ever existed!)
