Need to Fix Multi-Pair Testing Issue

We've developed an MT5 version of our EA and we are finding that the multi-pair strategy testing feature in our EA isn't working as expected. 

For example, let's say we are interested in testing EURUSD, GBPUSD and USDJPY.

So I set these 3 pairs in the tester settings. 

And I choose 1 of the 3 pairs for the symbol in the tester. 

However, no matter which pair I select of the 3 pairs, it yields a different result in the tester...

Even though the EA settings in the tester are exactly the same. 

Here's a short video (no audio) to demonstrate the issue :  https://www.loom.com/share/1cb65b04baeb41d6a0630536f5c9ae88

And I've also attached screenshots of each test so you can see that each time we ran the test, we got a different result even though the EA settings are exactly the same. 

We really want to figure this out ASAP! Hoping to find someone who has experience with multi-pair testing in MT5 who can help us figure this out. 

I understand you will need the code to figure out the issue, however I don't want to hand out my code to just anyone. So please tell me if you have previous experience or ideas to fix this issue. 

If you can show that you have a multi currency EA that is already working in the tester where you can select any pair from the pairs in the EA settings and it gives the same result each time, then the job is yours!

Otherwise, please describe your experience. Thank you!
