No hack or EMP on Orisa's Ult and other objects

I’ve noticed lately that neither my hack nor emp cancels Orisa’s ult (as well as hammond’s ult and sym’s turrets) despite the game showing that they’ve been hacked. This has happened several times but it always happens with Orisa’s ult and Minefield since the end of the most recent (2018) winter event.
Anyone else notice this?

I’ve noticed EMP not disabling Orisa’s barrier sometimes. (Already set up before EMP)
