1. Do you have the experimental kao garden stuff loaded? If so, does the issue persist even if you turn it off?
2. Can you clarify what you mean by "old"? Are you referring to the plants from a previous patch appearing, even after you close the window? Is it holding onto plants even if you try moving them? What/Where specifically are the "old" plants coming from?
By “old” I mean that a previous patch arrangement was showing up under the current arrangement. So as you can see in the picture multiple plants were occupying the same space in the patch.
I have the Kao garden improvement toggled on in experimental settings. I do not have chaos mode turned on.
I can’t tell you if toggling the experimental setting off would have fixed it, because I already manually removed each of the plants. And another strange thing happened. When I filled the patch back up with new plants I had to do it a few times, because some of the plants were not showing up in the garden after they were added and saved. For example, I would fill up a row with three pumpkins and save it, but then only one would show up in the garden, so I would have to go back and add them in again. But I eventually I got them all to save and display properly.
