missing sections of close captions and I've tried all the fixes.

On ALL stations - networks and premiums, about half the closed captions are missing. Has gone for years. DirecTV wants me to pay $400 for an upgraded Genie which is ridiculous. No wonder so many people are going to streaming services where it is not a problem. Does anyone have a 'fix' that will correct the problem? I think it's a problem with the 'Genie 1 Box' but it's been changed once and the problem has corrected. After 25 years I'm about the discontinue my account.
