Already reported in the 4e sheet thread. However, the values are correct it's just the display that's wrong. If you select the first "Ref", it will be saved as "Fort" in the relevant attribute. For example, if you pick the first "Ref" from the dropdown you've got a screenshot of and then use @{mba-def}, the result will be "Fort" while if you pick the second "Ref" the result will be "Ref". The same is true for @{rba-def}, @{iba-def} and @{power-def} with their respective dropdowns.
