It could be that they are being cancelled and rebooked because of an incorrect detail when executed. The commission amount might be changing, it might have been booked to the wrong account, fat fingers with a broker code, part of a larger order, or any one of multiple reasons.
While the market requires a certain number of fields to be declared upon execution, there are many more fields not reported to market on execution, but reported to the regulator by T+1, and if anything is incorrect it must be changed.
So, although it looks like nothing has altered, it may have done so in the background info.
The trades should all match up to the exact time of execution.
I have not looked back at what has been reported, but it is not uncommon to see cancel and rebooks
