typeface not showing in full characters

Recently I have tried to do some typography work on my outstanding projects. And unfortunately I have ran into a problem with displaying 2 of the typefaces and all of their available characters to view in the INSERT CHARACTER docker on the right of the screen. The message I get when I try to view the entire alphabet is  "install or download to preview glyphs". The typefaces are open type. I have used corel draw for years and never encountered this issue. I have removed any double installations and only have the 2 version normal and bold. See the picture for ref. Thanks to anyone who can help. I can offer more information in case I have left anything out to help the case.
