CBS Sunday night guide doesn’t match actual time

I have noticed over the past few weeks that the guide is showing that 60 Minutes starts at 6:30 but it actually starts being broadcast at 6 o’clock which is the usual time. This messes up the recording on the DVR because the DVR doesn’t start recording until 630 and I miss the first half hour of that show and every other show on that channel after that time. Could someone please fix the guide so that it matches the actual broadcast times so I can record them? Thank you
