Rend icon not showing sometimes

I’ve noticed that sometimes the icon doesn’t show. I was clearly hitting stuff and the icon didn’t show. Also. I had a lone mob and I got close to it. I went up to it to hit and then back away. Rend didn’t apply but bloodshed rune?? Did happen. Had the ticks going. Idk.

Same thing is happening to my barb. Have Ambo in the cube and everything. Even if I do the rend skill, nothing. My non seasonal barb shows it no problem. There’s nothing different between my seasonal and non seasonal barb
