I think a rune knight in my collection is showing the class featuees of the eldritch archer for some reason. Went into the editor to fix and it displays properly there, and it shows the feature names and selected options like shimmering swipe and chromatic carve, it just displays on the app and character sheet with the wrong descriptions.

Tried switching to web browser, tried reloading, nothing doing. Is this a Tasha thing?

Please post a link to your character sheet so someone can look into it for you.
