I created a new bench and a site, and I installed my apps from the previous bench to the new site. The apps installed successfully, but the added DocTypes are not showing up. I also tried the bench build, update, and migrate commands.
If you create a custom doctype, and “Is Custom” is checked then it will store in the database, it will not store in the custom app or module, but if “Is Custom” is not checked then it will store in the module or app.
yes it is already linked
custom option is unchecked but still not resolved.
Then you have to check the custom doctype in your custom app.
