Triple ligature editing affects existing double ligature

Hi, kinda new to this so sorry if this is a simple question.

I’m trying to make custom triple ligatures, eg. v_o_l, but when I edit something in that glyph (the v in this case), it makes the same changes to the double ligature v_o that I already made. Is there a way to unlink these?


Decompose the ligature. That will break the link.

Do you used components in the ligatures?
