[O] Bug: Capital lettered plain lists export as numbered

[Scott Otterson]

In my org file, I have ordered capital lettered plain lists like this:

A. Item A

B. Item B

    a. subitem a

    b. submitem b

C. Item C

But when I export them to a pdf via latex, they look like this:

1. Item A

2. Item B

    (a) subitem a

    (b) submitem b

3. Item C

Is this a bug or is it expected behavior?

--- test .org file ----------------

A. Item A

B. Item B

   a. subitem a

   b. submitem b

C. Item C
