One of my player realised that while we gained level, the proficiency bonus is shown in the character sheet in the core stats page, it does not increase the saving throw, attack rolls and skill check. The problem is in all my characters sheets and I checked if the problem would be the same with jack of all trades, proficiency and expertise and it is. My rogue (Drax) how have a dexterity score of 18 and expertise in acrobatic and a proficiency bonus of +4 (they are now level 9) show a bonus of 12 but when roll the skill check it only count 1d20 + 4 (dex) + 2 (proficiency) + 2 (expertise) instead of 1d20 + 4 (dex) + 4 (proficiency) + 4 (expertise).
