Back testing inconsistency issue

[rodger Kilonzo]

I have built a trading bot , and when i back test it from may last year to now it is profitable genarating 57% profit when risking 1%, but  the issue is when i back test from january last year the bot does not produce the same results within the same period it was profitable that is from may to now. and it does not make any sense unless there is an issue with the back testing tool , please assist
