Custom signs y-offset no effect

Can anyone explain to me why Y-offset values don’t seem to have any effect when I enter them in the custom symbol field? (e.g. when I create a new symbol for a playing technique). Thank you!

If you mean inside the playing technique glyph editor, I think they work in relation to each other when you have more than one glyph.

OK, I thought they would shift the position of a sign in the score.
