hi, I'm wondering if anyone has the solution to this problem. I've changed the scheduled size in some tree symbols, but every time the plant list recalculates the sizes show up as a #1 pot. I have no idea how to solve this other than editing it manually, but of course it defaults back to the wrong value every time I open the drawing. Can someone please help. I've tried all the fixes that seem obvious. I've never had this problem until updating to 2021.
