Contract Bug in Career Mode - Needs to be Fixed Quickly

After a certain period in career mode, signing or renewing player contracts becomes nearly impossible. We're particularly frustrated by the fact that we can't sign players with six months left on their contracts, forcing them to leave the team for free after their contracts expire. We start the season with enthusiasm, but as the months go by, we lose almost all of our iconic players.

This significantly diminishes the enjoyment of the game.
This bug needs to be addressed quickly; it shouldn't be this difficult.
