Primal Knowledge not reflecting in character sheet when Rage is activated

The rules glossary:

Passive Perception is a score that reflects a creature’s general awareness of its surroundings. The DM uses this score when determining whether a creature notices something without consciously making a Wisdom (Perception) check.

A creature’s Passive Perception equals 10 plus the creature’s Wisdom (Perception) check bonus. If the creature has Advantage on such checks, increase the score by 5. If the creature has Disadvantage on them, decrease the score by 5. For example, a level 1 character with a Wisdom of 15 and proficiency in Perception has a Passive Perception of 14 (10 + 2 + 2). If that character has Advantage on Wisdom (Perception) checks, the score becomes 19.

The barbarian's Primal Knowledge skill:

Level 3: Primal Knowledge

You gain proficiency in another skill of your choice from the skill list available to Barbarians at level 1.

In addition, while your Rage is active, you can channel primal power when you attempt certain tasks; whenever you make an ability check using one of the following skills, you can make it as a Strength check even if it normally uses a different ability: Acrobatics, Intimidation, Perception, Stealth, or Survival. When you use this ability, your Strength represents primal power coursing through you, honing your agility, bearing, and senses.

The character sheet's Passive Perception score remains at 10+WIS modifier rather than reflecting what is should (10+STR modifier+5 (for the skill's state being "Advantage")).

None of the skills listed in the Primal Knowledge description are flipping to STR as their governing score as they should, nor are they getting the green "A" next to them for being tied to a score (STR) which should be in a state of Advantage (Rage states: Strength Advantage. You have Advantage on Strength checks and Strength saving throws.)

The sheet is correctly placing Athletics (which is naturally tied to STR) in an Advantage state (it gets a green "A").
