Stop limit orders

Can someone help clear up my understanding. I had an Isolated brief for FTM with a stop limit order to purchase at trigger worth zero.1945 and a limit order worth at 0.1954. I can see the worth obtained up to 0.1945 so set off the limit order to be placed. The worth didn’t go any larger yet the limit order was crammed? How does that happen?

From my understanding and from studying the documentation, there's the preliminary set off worth which then places the restrict order, so only if the restrict order is hit should that be crammed. Is that right?
