UI still attach after spectating

So apparently i play RedSec with my squad, i was downed and spectating my friend. He used the Tank paint tool (idk what it is) to look enemy in front of area. Then my redeploy timer is up and i redeploy but the UI of the tool still attach after spectating him, i don’t know why even i tried to open the menu it’s gone when i close it appears again. I hope you guys understand what I’m saying 

thank you, see ya in Battlefield o7
