Plans Last Finish Time date is incorrect

Hi everyone, I'm having problems with some servers, the agent local shows "Last Finish Time" an old time (almost 1 year in the past), but If I look into plan history it shows the daily execution correctly...
The plan is running fine every day.. but due a some unknown reason local agent on the serverver being backed-up is not taking the right date.

Anybody know why this could be happening?

I've updated agent with last version. Rebooted server. Ive seen this behavior several times... If I run the plan manually it update the date correctly. But with schedule execution it loses the right date again.
