changing UI font

Keyborne - Raging Tide

recently i noticed ( through no changes made ) that the font size on one of my toons accounts was smaller than the rest. The UI settings were all the same for different accounts and toons but this one toon was showing much smaller fonts - screenshots attached

tried looking around for a way to fix it cos its kinda hard to read when it comes to quest-log text and especially annoying when switching to another toon

normal toons/accounts
