ABC STL region brief video lag persistent

I have a Directv Satellite Dish for years in the St. Louis region in Illinois.   Recently,  we've noticed a video glitch/skip that is occurring persistently.   Audio is never disrupted, but the video picture will freeze a split second and then jump right back in sync with audio.    This occurs about every 15 to 45 seconds.    I noticed it on Sunday and again Wednesday.   I reached out to another neighbor who has a similar setup, and they saw the same issue.    I switched to the Directv app on my phone and on the tv, and the glitch/skip never occurs. 

I've checked all other local channels in St. Louis, and none of them have this problem except ABC KDNL .   I checked various other channels like ESPN, HGTV, FREEFORM, ION, etc .   None of those are showing a glitch/skip either.     It's annoying to watch .    I have other options but I would rather not have to switch to the Directv app when I have no issues watching any other channel.
