Vampire 5th Edition - trying to modify character sheet

Hi All i'm trying to experiment with the Vampire 5th edtion character sheet so i can change some terms, maybe some minor design elements for a potential period set game. i've got the HTML and CSS code from Github and have copied that into the Custom Character sheet part when setting up my game - so far so good, The preview pane looks normal. However when i log into my game and create a character, the sheet looks odd - all the attributes, skills, and fields have been replaced with [(original name) - u] and have changed to a red font. Now i can see that -u in the HTML code, but so far i've not altered anything - this is just a straigtforward copy/paste from github before i even attempt to break it... :) have i missed something here? Cheers Chris

If that sheet is set up to handle translations (which I think might be what is going on), then you need the translation in the 3rd pane of the editor.  At least that is what I think is going on.  

That's almost definitely it. You need to fill all three panes (if content is available) to make the sheet work.

That's done it -thanks for that! Now, to work out what else i can change... :)
