I then save it and close Pd, but when I open the program again some of the “$0" are replaced  by “_\$0” breaking the program (as in the pdf I’m also sending, but I’m not sure if you would be able to see it). I can easily edit it again, but every time I reopen the program I have to do the same.

Is this something I should report as a bug? the thing is that I don’t have a reproducible examples and I think this is highly dependent on the screen setup. However, may be making sure that canvases are not saved with negative coordinates could fix the problem.
