Thanks. Since your proposal was to have even number of options, would you please also add the century (or something similar).

@mmahmoudian Actually the logic that add format buttons ensures that there are even number of formats passed. So before threre were 21 formats (including century) and it was only adding 20 formats excluding century but now since i added 1 it has become 22 formats and its showing all 22 as its even.
