These pages rectify three types of errors in Proc. Amer. Math. Soc. 146 (2018), 909–920.

We specify that $u^{0}$ depends on the fixed subfield of the unitary involution.
We extend the definition of Springer’s property for unitary involutions and re-prove Corollary 3.5 only for quaternion algebras.
We add assumptions that characteristics of residue fields are not 2.
