Lightroom displays monochrome profile

Since the latest update to Lightroom Classic when browsing profiles in the Develop module, I have found that the image occasionally remains in  monochrome even if another profile is chosen and will not respond as usual when pressing the Alt key and adjusting the white and black points. The only remedy appears to be to select another image in the filmstrip and return to the image being processsed.
