Renaming files using tags


I've got one problem with Mp3tag 2.33. When I want to change file name, using tag - filename option and mask:
%artist% - %title% [%comment%]
the result I get is:
artist - title comment

When I've been using Mp3tag 2.26 everything was working fine - after using such mask I've received file names:
artist - title [comment]

What should I do, to correct this problem?

Use %artist% - %title% '['%comment%']'
