Unexplained failure with the supplier

Hello, the situation is as follows: This price list was previously linked and on 6.09 116 positions were missed (we did not need them). Some kind of failure occurred on the 7th. The price list did not change, when loading the price list, the fine settings did not change! We decided to experiment on the 8th: we loaded the price list at 12:45, started linking the positions, since they were previously loaded and now we have to link them in the "Not in the price" mark. Then at 14:31 the same price list WITHOUT FIXES was loaded again and there were more missed positions and those that were connected "got rid of". 1.09 everything was fine and there were 41 positions missed. Is it possible to somehow "roll back" and find out what parameters were specified in the fine settings? When was the price uploaded earlier? And what is the reason in general? It is not realistic to link 600 positions manually each time. The screenshot is attached. How to return the parameter
