Glyphs are replacing text, even when that functionality is disabled [see animated GIF example]

This is happening with various typefaces that have glyphs for certain character combinations. I am trying to type the word "confidence", but it keeps turning the "fi" into a glyph that merges them into some kind of single character. I assume this character exists for another alphanumerical language, but obviously is a neusense for english writing.

NOTE: I have disabled this feature under Photoshop>Preferences>Type>Enable Type Layer Glyph Alternates... With that enabled or disabled, the same behavior persists; even if I type the word fresh into a new text box. This also occurs with other typefaces (e.g. Myriad pro, Lato, etc...) but not with those that don't appear to have that "fi" glyph (e.g. Arial).
