Leaf (fan) damage does not necessarily rule out that a plant is acting as a dormant. The cold hardiness of leaves could be independent of the cold hardiness of shoot apical meristems (growing points). In general plants are more cold hardy when they are not actively growing and less cold hardy when they are actively growing. Plants are less cold hardy (or not cold hardy at all) if they are not cold-acclimated in comparison to when they are cold acclimated.

Your plant is actively growing and may have lost its cold acclimation.
