Lightroom previews RAW files correctly, then after loading displays colours that are not in the file

As I started editing photographs I took in February I noticed that LrC will show previews in what is the expected colouring, then after loading the file it will look like the example I am posting. Strangely though, the file in  a different program has the proper colouring (without the stripes). Whatever did Adobe do in one or more of the updates that went past my MAC? I dread using LrC, it used to be my favourite program.
