Does Stop-Limit Open Order change once Stop trigger met?

I set a Buy Stop Limit order as such:

Stop Price: >=3460

Limit Price: 3380

My understanding of this trade is that when the price rises above 3460, it should immediately place a Buy Limit Order at a price of 3380, meaning that when the price drops to or below 3380 I will buy the coin. Is this correct, firstly.

Secondly, I watched the price rise above my Stop Price, stay there for a while, and then drop below it again. Nothing changed in my Open Order though. I was expecting it to change into a Limit Order. Have I done something incorrect, or is my understanding faulty, or did something not work like it should on Binance's side?

Definitely went past Stop Price and stayed there for a while.

Open Order didn't change as I was watching it go past trigger price. I was expecting it to change into a Limit order at the price I set...?
