Low Number of Agents Used Anytime I Backtest Lately


I'm working on dialing in EA settings for a MT5 EA and have been utilizing the agents available from MQL. There used to be anywhere from 200 to 500 agents used at any given time as long as I had enough money in my account... However, for the past couple of weeks it starts there and then within an hour drops to teen or single digits being used. I'm in the US and typically connect to the MQL5 Cloud USA 2 network but have also tried disabling this one to force it to connect to MQL5 Cloud USA and ran into the same issue.

Has anyone run into this before? What can I do to resolve this? 

Thank you in advance!
