No statistics for favorites in negotiations

I prefer to follow some times performances of players, who are presented in negotiations list, or are available for direct offers (from friends or participants of same tournaments) before making the offer, but unfortunately all statistics data is disappearing after I add them to favorites list
I cant see statistics even after clicking of players data via managers profile
Do other players have the same problem?
And is there any solution for it:confused:

Maybe he hasn't played for his new club. Try looking at some others? I just did that and there where stats. They are reset at club change/transfers

Some of them were still in the same club
even if the player has not played for current season it has to have overall statistics, but there is 0 in all columns
