Open the door(s) and find the check strap. It is the device that hold the door open. If your's are original, then they will be painted to match your exterior color. If they have been replaced, then they will be sort of a brass color. If original, then you should replace them as a preventative matter. You really don't want to close a door against a seized check strap.

Put your finger on it and move the door towards closed. You should be able to feel it resist and maybe vibrate.

Replacements are cheap and the procedure is dirt simple after you get the door panel off.

Frankly, very strange for both check straps to go back at the same time. Even more strange that the strike plates are bad at the same time.
