VNKI won't go away!

[js190]

My current DO backtest outputs positions like:
system.accounts.get_optimised_position_df()

But some of these instruments e.g. VNKI are in the in the bad_markets list, why are these appearing as positions?
Is there another method to call to see the results of the optimisation with the trading restrictions and bad markets taken into consideration?

------ update below:
Ah, I think I found it. Looks like an issue in the caching:
There's so much caching going on in basesystem.py, it seems that somehow we cache an incorrect state - maybe before the yaml with exclusions is loaded?
