[5e Community] Expertise and Proficiency doesn't seem to calculate properly- seems to be not calculate proficiency bonus correctly

My Bard is level 6- Proficiency bonus of 3 and Charisma Bonus of 3- He should, therefore, have a plus 9 on his persuasion rolls in which he has expertise. I have a similar problem with proficiencies also, it seems to calculate it as my charisma modifier + a proficiency bonus of 2 when my proficiency bonus is actually 3.Changing my levels higher hence changing my proficiency bonus to 4 does not affect the rolls either, I seem to always get a plus 7 modifier on an expertise roll regardless if my proficiency is a 2 or 3 or a 4. I think my sheet may be bugged in some way surrounding my proficiency always calculating as a 2 when it is no longer a 2 and was hoping if there was a solution.

Hi, Tom H. Which of the three Character Sheets for D&D 5E are you using?

The community contributed sheet i believe

Try looking for an Attribute (on the Attributes & Abilities Tab ) of the affected Character named PB and delete it. If this fails to solve the issue, please post a screenshot of the tooltip of an Inline Dice Roll displaying the issue.

The sheet did not have a PB roll so I assume was defaulting to 2, I added a new PB into the attributes and abilities tab which appears to have fixed the issue for now thanks
