Josef Pro font disappears as you type
I am trying to type the word "Communications" in Adobe Illustrator. If I use any other font, it types fine and looks fine. When I use Josef Pro, the "ti" goes missing and only shows "Coomuncaons". When I change from Josef Pro to any other font, I can see the "TI". I tried this is other applications such as Microsoft Word and Excel and this problem does not happen. It's definitely an issue with Illustrator.
Unfortunately, I cannot use another font because our company logo uses this Josef font.
Please help.

It seems like the font tries to replace 'ti' with a ligature, but then it fails to load one from the font itself. Unchecking the 'Standard Ligatures' button in the Window > Type > OpenType panel could help
