Default font is NOT the default one

Hello :)
So I have a Sony Xperia L and it had issues today like it was rebooting itself endlessly so I did a hard reset (and my phone was rooted before). The hard reset did well but the font that I installed with my root didn't go. How can I turn it to default again? I used the app "HiFont" to install the font, and my phone is now totally new EXCEPT the default font. Thanks in advance :) (and sorry if my english is not really perfect :/)

After a reset, everything you installed is gone. Download the font again and set it as the default. The phone is looking for your default font, not finding it, and using its default font.
