Those are the settings for the hooking label, but where are the settings for lsxcommand itself? You need both, AFAIK. In my theme the label is cmdlabel, and it looks like so:

cmdBorder 2

cmdLabelX $dateTimeX$
cmdLabelY $mainbarGroupY$
cmdLabelWidth $dateTimeWidth$
cmdLabelHeight $mainbarGroupHeight$

CommandX $cmdBorder$
CommandY $cmdBorder$
CommandWidth $cmdLabelWidth-2*cmdBorder$
CommandHeight $cmdLabelHeight-2*cmdBorder$
