Rookie Contract Extensions

We seem to have a potential flaw in extension demands I wanted to note here and maybe it can be reviewed? It is related to guys on rookie contracts (or potentially may also apply to any player on a 4-5+ year deals but seems to be related to only rookies). Essentially, we have star rookies that are on a lower rookie wage scale based on their draft pick. So for example, the #1 pick in our draft is being paid $5.5 million for 5 years. Based on settings in our game, his demand extension asking price should be north of $10 million as he is 91 OVR. But he is only asking for an extension of $5.7 million and will sign an extension for 7 years even though he is still a rookie in year 1 of his rookie contract.
Same thing with the #2 pick in draft. 93 OVR RB that based on setting should be demanding near $10 mil or more at the very least. BUt just signed an extension for 7 years at $5.5 mil.
Extension demands work well overall in other areas and for other players but wanted to check if the demand logic can be looked at related to this aissue where teams are able to lock up rookies for 7 years for basically the same price as their rookie contract. Doesn't really make sense for players to be talking extensions during their rookie year anyways until they are closer to free agency. Often when I try to extend veterans in the first year of a 4 or 5 year deal, their demand price is super high (which makes sense) but this same logic doesn't seem to impact rookie contract / young players.
Update: it doesn't seem to impact lower rated rookies as much. It's almost as if there is a cap in place for how high rookies will demand. Which makes elite rookies demands seem really low. Maybe doesn't impact everything single rookie the same way but odd to see the #1 and #2 pick sign 7 year extensions two weeks into their rookie season for half of what the settings would suggest.
