Ever Upwards Not Activating?

I have a Valkyrie Queen with the trait Sentinel and Ever Upward. Sentinel allows my Valkyrie queen and allies adjacent to her to automatically defend and provoke at the end of her turn, and ever upward allows her to resurrect all allies with 50% HP every time it defends starting from the second time it defends. However, the “Ever Upward” trait never seemed to activate, even when my Valkyrie Queen has automatically defended twice or thrice. Does Ever Upward ignore auto defend as a valid defend? Or is there something to the trait I did not get?
