PF_ADD_POPUP issues in Premiere Pro

I have a plugin with a popup that functions as expected in AE. In Premiere it only displays the first option. And even though I can click on other options - the UI does not display the changed option.

A_char* popup0 = "Preset1|""(""-|Preset2|""(""-|Preset3|""(""-|Preset4|"
        "(""-|Preset5|""(""-|Preset6|""(""-|Preset7|""(""-|Preset8|""(""-|Preset9|""(""-|Preset10";
    PF_ADD_POPUP("Presets", 1, 19, popup0, TYPE_ID);

In. the header,

enum {
    Preset1=1,
    PADDING_1,
    Preset2,
    PADDING_2,
    Preset3,
    PADDING_3,
   Preset4,
    PADDING_4,
   Preset5,
    PADDING_5,
   Preset6,
    PADDING_6,
   Preset7,
    PADDING_7,
   Preset8,
    PADDING_8,
   Preset9,
    PADDING_9,
   Preset10,
    Num_Choices
};
