Question
Why some fontawesome glyphs are present as text and some as images?
I have a problem when some glyphs is presented as text (as on screenshot 1) 
and some text is presented as icon (as on screenshot 2)

Both of them have same font "Font Awesome 5 Pro" and same font attributes - size 16 and weight solid.
It is clearly local problem because other people don't face it.
Any tips I can make this work?
