You know what, paekae - it was exactly that! Thanks!
Turning the setting off sent out one final “POP!” when I closed the preferences dialogue, but now there are zero pops in the exported file.
Thank you so much. I love this place and people like paekae. They must’ve seen it thousand times already, but still care enough to restate the solution for the rest of us.
Ps. If anyone knows why this happens, I’d be interested in an explanation.
