You probably didn't install the English patch correctly. Here's a step by step by guide from the readme:
Installation instructions
----------------
1.) Copy all contents of the patch into the game install directory
2.) Rename obj.vfs in game install directory
2a.) If this is too complicated, run the setup.bat included
"Do I need to install the Japanese 1.02 patch?"
It can't hurt, but I'm pretty sure all the files changed are encompassed in the English patch.
You probably didn't rename/delete obj.vfs. Seeing as the English files from the translation seeks to replace those as individual files and that's the packaged Japanese files taking priority.
