Expense code detail does not match documentation after upgrade

We have defined values for UDF codes in different expense categories, like

Category Airfair:
yes
no

Category Meals:
yes
no

Now in version 2012 SP1 UDF can no longer be defined seperately for each expense category. How do we avoid duplicates?

During the upgrade, Changepoint concatenates category name and code value. So after the upgrade you will have

Airfair: yes
Airfair: no
Meals: yes
Meals: no

Please note: The release notes mention the result would be like

yes (Airfair)
yes (Meals)
etc...

But this has been changed last minute so the result after the upgrade is in the format as mentioned first.
