Unknown actions appeared in web charlist, not custom

Hello.

My player plays Goliath Barbarian (Path of the berserker lvl 14), ruleset 5.5. Recently (we played 21 may, it didnt appear) my player asked me what means new actions in Bonus Action section.

I opened his charlist and saw Furious Onslaught and Red haze with some description (extra attack and dmg reduction 5, also can attack teammates when raging). Tried to click on these, but got popup "Content Error We couldn't find that content! Please try again." 

Also tried to find them by searching dndbeyond website but find nothing. Mobile app(android, harmonyos) is fine.  Clear cookies\cache didnt help.

Sure, https://www.dndbeyond.com/characters/155872133

Found a solution with this problem whe i was reading neighbors post of contents error.

It was element of crooked moon dark bargain unquenchible rage. I then added this bargain to the character sheet, and then removed it. Workef (the feature disappeared)
