STOP LOSS not REGISTERING AS A TRADE

[mik-s]

When a stop loss is hit there is no signal being generated back to backtrader. I've worked with direct borker APIs like OANDA and when a SL is triggered, notify_trade would occur. For that signal, logic could be set around SL management.
I've placed print statements throughout the mt5store and mt5broker methods and nothing is being triggered when a stop loss is hit. However, when a position is manually closed using the MT5 terminal, a signal is caught be Backtrader - verifying that there is feedback coming from mt5 on orders/trades.
Any thoughts on what could be causing this? Does it happen to others as well?
