i tried too renew a few contracts.I have some not showing contract on the player card.I was able too renew some others. I do have room under the cap.I am not sure if this is a bug or not.

scratch that, misread

If the contract button is missing then they are probably not eligible to renegotiate. A player cannot renegotiate their contract in the same year that it was signed.

These are showing last year contracts.

Were they 1-year deals?

This i have no clue on.I took the team over this year from someone else.They may be 1 year deals.

You can look in the player's "transactions" tab to see when they signed their current contract. But if you can't offer a new contract they are almost certainly 1-year deals.
