Sorry for late reply. Can you please tell me which font that not changed yet?
Also, actually i’m not familiar with this font and if you can tell me more detail when you ask something about this font it will much help me.
Did you mean that there’s some string that not using the sans-mlym font? Because it seems you will need to do some string translation by using JNews Frontend Translation plugin. You will need to install and activate this plugin to do frontend string translation. You can check our documentation about it here http://support.jegtheme.com/documentation/frontend-translation/ and find Frontend Translation section.
