Got different retest results while retesting same strategy with same data, Why?

I was using custom project to generate trading strategies, and I used different databank to place strategies for different step.

Then, I found that when one strategy come into different databank, it could got totally different equity curves even with totally same retest data.

I’ve campared the source code of those strategies, they are all the same except StragetyID.

I am wondering how could this happen? Is there any thing I did wrong?

Can you share an example? Once the testing configuration is loaded correctly (from the strategy config) there is no specific reason why it would differ
