Backtesting - Strategy analyzer randomly skips time periods

Hi there,

I have the problem that the strategy analyzer is skipping certain time perionds when running a backtest. But if I set those skipped time periods in a second backtest (with everything else leaving the same) it works and the time period is recognized and trades are recorded.

E.g.:
I test for the time periods: 01.01.25 - 20.05.2025
Period skipped: 15.03.25 - 30.04.25 - so no trades recorded in the backtest

If I chose exactly this period in a second test (so 15.03.25 - 30.04.25) trades actually ARE recorded in the backtest, although I leave everything the same ecept the time periode.
So in one test trades are recorded in the other one not.

Sometimes, if I run a THIRD backtest with the original time period (so 01.01.25 - 20.05.2025), then it suddenly works and 15.03.25 - 30.04.25 is recorded as well.

How can I ensure that all dates are recoreded/backtested properly?
