Ship's journal editor problem
 

I have a little\big problem with the jse in my campaign (WoS). Putting it shortly, having just started to play SH5 and having never tried anything even slightly similar, I decided to save scumming in the first two days of my campaign, to make a bit of easy practice with the real navigation mod during the attack plotting part of the game. This continuous save and reloading, that included the journal, had brought to a situation where each of the auto sub data loggings and some hidden entries have multiplied themselves several hundred times, making the sje quite bulky and really difficult to load. I deleted manually the hidden entries, but, through the editor, I can't touch the auto sub data loggings. If I try to open the .sje through an editor and delete manually the long sequences of repeated strings, the file gets corrupted, and can't be open either in-game or in the editor. So... how can I resolve my issue? Any one knows in what language the file is written? Thanks for your time.

P.S.: I don't know if the mod thread is the right place to post this, but since my issue is revolving around a mod and not the game by itself, I thought so.
