[I've got two assistant managers...]

Is this supposed to be fixed in new saves only, or for existing games as well? My current save has three assitant managers, as you can see - two old assistants and my "real" assistant manager:

I'm on version 21.4.0.1529005

[Previous matches are not saved.]

I presume this is a bug which only occurs for some users, as I seem to be able to view match reports fine as noted in the thread 

Hence why a save game was requested, because some/most users aren't hitting this issue?

It works for me on PC as I've just shown with screenshots in the thread below:

 

[How are people viewing match reports?]

I can do this - e.g. here the Oldham game is my penultimate fixture, and in the second screenshot the result of clicking on the score (I am playing on a PC, in case that is relevant). I did have a transient issue before where clicking on the "Watch goals" item at the top right of the match report screen did nothing, but that has gone away now and "Watch goals" works again - no idea what changed to make that bug appear then go away, other than fiddling with window-mode for the game rather than full screen, then back to full screen, although that is probably a coincidence.
