Showing incorrect Boss Rush completion currently in Season 2

Now it’s season 2, I expected all Boss Rush completion values to have reset to “zero” completed this season (as I have not attemped any yet!). This seems to be right on my profile page, but it’s showing different values per character when I begin Boss Rush:

For example, Grave shows I’ve already done 7 Best:

However, they are also incorrect, as Geiger shows I’ve done 8 - which I didn’t do in Season 1, nor current season:

I’ve encountered the same issue.
