Hi! The random openings for Brazilian draughts that you put on here (FMJD tables) should be only used in Russian draughts. There are 9 openings that are probably already lost because of the rules - Brazilian players took Russian table with 745 openings and after analyzes deleted 9 which are not possible to play here. You took the FMJD table for both Brazilian and Russian version, and i can see that some of them are even not possible to setup: position 1 - IX from the list is ab4 ba5 ed4 dc5 bd6 ce5, which is illegal because the rule of majority. The correct table you should put is here:

The first table is for Brazilian draughts, there are 736 openings. The second one is for Russian draughts, there are 745 openings.

Another example of the opening that is not possible to play, is here, one of lidraughts users made a study showing how its lost, and with the computer analyzes showes that this analyze is correct:
