I loaded the Adobe InDesign CC Ap from Creative cloud, version 14.0.2 x64. The file I had used before now has missing text! Specifically the "fl" in the Active Ingredients list "Isoxaflutole" which now appears as Isoxa utole" throughout the whole book with empty space for the "fl". Even the word "flowables" appears as " owables".
The file seems to have "Ligatures" checked in the character palette which I did not check. I'm using Helvetica fonts.
Any suggestion as to how to get my text back? See attached files.
