In the 2021 version of InDesign, the bold version of Adobe Caslon Pro does not work. It leaves a blank space, and if you click on the opentype box, it says "opentype properties are not applicable." The font itself is not the problem...I cannot reinstall the fonts because creative cloud tells me they are already there. Caslon and all its versions are also correctly installed in my windows fonts folder. I also cannot export to a PDF when I have the bold version of Caslon on a page. I CAN see, print, and use the bold font in older versions of InDesign. Something is wrong in 2021 InDesign and needs to be fixed.
