I was dealing with a text “problem” that i didn’t recognized how to fix it.
I searched soem topics online and in Figma’s website, and i didn’t found a solution.
A tip to this kind of situation is very simple to resolve itself.
In the Type Settings box, there are a section called “Letterforms”, and then you have the “problem”: Ligatures and Rare ligatures. They make a conection with some letters, specially “S” and “T” (as demonstrated in the screenshot).
