Don't propagate anchors doesn't work?

Here we see the Burmese 6 with its dotbelow anchor used for positioning the dot below the numeral. As you see I have propagate anchors turned off, but the 9, a flipped component of the 6, somehow manages to inherit the anchor, flip it with the component and then push it inside the letterform. I don’t want the 9 to have this anchor at all.

I have fixed it. It was only applied in export. But not in the UI.

It’s anchoring incorrectly in the exported fonts, same as in the preview above, is that what you mean?

It should not anchor in the exporter font. I’ll check again.
