Your results show that AUDCHF made the most profit but only with 1 trade. So you might want to give it a bit more time.
Also, the AUDUSD performed well with 4 trades.
Remember that these EAs are based on non-martingale systems, so there will always be stagnation periods.
As I’ve mentioned in another thread, if the EAs are in a losing phase, I don’t put anything on the challenges but wait for the next profitable run.
