When importing a monster, I am getting issues where the proficiency bonus is marked as added, but isn't adding. Unchecking and checking fixes the issue. The same with text in the abilities section.

I used the following statblock (made one myself to avoid any IP issues)

CON
20 (+5)

Damage Immunities poison, psychic; bludgeoning, piercing, and slashing from nonmagical weapons that aren't adamantine.
Condition Immunities charmed, paralyzed, poisoned
Senses darkvision 120 ft, passive Perception 15

Herbivore Rage. When Super Cow is engaged in combat with a creature that has eaten meat in the past 72 hours, it deals an extra 10 (3d6) damage per attack.
ACTIONS
Multiattack. Super Cow makes 3 attacks, 2 with its bite and 1 with its horns.
Bite. Melee Weapon Attack: +11 to hit, reach 5 ft., one target. Hit: 15 (2d8 + 6) bludgeoning damage.
Horns. Melee Weapon Attack: +11 to hit, reach 5 ft., one target. Hit: 19 (2d12 + 6) piercing damage plus 6 (1d12) damage if Super Cow moves more than 15 ft. in a straight line toward its target on that turn.
LEGENDARY ACTIONS
Super Cow can take 1 legendary action, at the end of another creature's turn. Super Cow regains spent legendary actions at the start of its turn.
Flatulence. Super Cow rips one. All creatures in a 60 ft. cone directly behind Super Cow must make a DC 15 Constitution saving throw, taking 14 (4d6) poison damage on a failed save, or half as much damage on a successful one.

Importing was successful

character sheet math is wrong, giving me my +6 str bonus to the attack, but not the +5 proficiency bonus

opening it up, shows that the proficiency bonus is indeed marked

unmarking, then remarking it fixes the problem

A similar thing happens to ability text - this is what happens when I click the herbivore rage ability

in the sheet, the text is indeed checked

again, unchecking, then rechecking refreshes it, and it works properly
