MT5 Strategy Tester - "Margin call level" and "Stop out level" not changing

 

I'm attempting to run a strategy test on one of my EAs. I'm emulating comission and a few other basic settings via the Delays and Slippage settings to ensure I'm testing with near-live trading conditions.


Although my issue here is with the "Margins" tab in the "Trade Settings" window after clicking on the small button next to the "Delays" item in the Strategy Tester. My "Margin call level" and "Stop out level" are stuck on 100 and 50 respectfully. Even if I try and change them to 50 and 30 and hit OK, they always revert back to 100 and 50. I've attempted many other combinations of numbers, yet no luck.


Why is this? These settings are crucial for me to test properly. I've attempted closing MT5 and restarting my computer with no avil.
