Oh no, The ones that are like at 50-50% % or something? Or maybe I'm looking at it wrong? Percentages personally confuse me in general so maybe it's just a me thing.

Ah, those :D It is not like the percentages themselves matter, the signs could probably be removed (I don't remember if they are automatic in the template or not).
Those bars are just meant to be a measure between two opposing personality traits. Like, innocent vs. jaded or shy vs. bold, or careful vs. reckless. It is quite common to have this type of system in IF, at least in Choice of Games style IF. Usually the personality will change some flavor text in these types of games, or may even tie into some key choices that will not succeed if you go against your established personality.
Of course, here they are just bars that roughly tell you the types of choices you have taken. They currently have no other purpose than just being there. The traits listed in then are also never perfect so I personally find it best to not pay too much attention to them.
