A question about training reports...

I've recently begun playing FM2020, though I have well over 1000 hours logged on FM2014. I have lots of questions but the one perplexing me most has to do with training.
I get the regular weekly training reports and in them, the same players are highlighted each week as having performed well in training. However, when I look at their progress, they are making none. They may have the occasional yellow arrow pointing up but the summary at the bottom of each column says no significant change.
In addition to this, I have some players who are never mentioned in reports who have made significant progress, some even improving three stats by one green point over the first three months of training.
Are these problems normal?

hey man i never check training ratings for player development unless to improve morale praise him when he performs well in training. my idology is this training rating is how well the player has performed in the training while progress means how much the training impacted the players to improve their attributes

Okay. Thanks for the feedback.
