What happend to footage?

Does anyone know?
I first saw True Grit (1969) about a year after its theater run, on television, and enjoyed it. I didn't see it again for many years, and when I did see it, something was different with one scene.
When I first saw it, the scene in which Cogburn finally meets J. Noble Daggett, the lawyer, amusingly "played-out" with Rooster betting all he had that Mattie would "make it." Daggett, with a little grin, replied "oh, no" the camera then moved in to portrait Daggett and he sombered-up and further replied, "I only bet on a sure thing". I can't remember for sure how the scene ended, but, the next time, many years later, After Daggett said "oh, no" the scene faded-out, uncomfortably, into the final scene.
The theater, showing, I saw, (as recent as a year, ago)
had this fade-out, including my VCR tape .
What happened to this missing footage, and why was it cut? Please advise.
