Trouble with post build script

I upgraded to JUCE 7.0.7 from a much older version (3.0.x) and I started seeing some errors in the post build script on MacOS. I deleted the MacOS exporter in Projucer and created a new one to make sure that any previous settings were cleaned up. However, after saving the project, I noticed that the post build script re-appeared in the new exporter and seems to be identical to the old one. It even has some code signing steps that are trying to use an old certificate that no longer exists. Given that there have been some changes to the plugin formats in the past few years, I’m wondering whether this post build script is really supposed to be there or if it’s just an artifact that was cached in Projucer. I’ve been struggling with this for a couple of weeks now and would appreciate any help.
