I checked the defects you posted, they are all closed and all showed as fixed in earlier 12.40 releases, so things should be good, but it looks like the poster before me figured out that if you had the issue previously, you may need to recreate the chart in the new version to get things working, doubtful that got into Release notes or anything, but since it worked for them, can you give that a try as well to see if that does the trick for you too, as if so, we can definitely get an Article created to warn folks they may need to do that if they run into the issue. I am not sure what about the object would be causing the issue though, the only other thing we could do is have you open a support case and attach the app in question, so we could have a look at things directly to see if we can spot anything.
