It seems to me that you have recreated the module in your application, when you download this module from the appstore the module will appear under the appstore modules section in the project explorer.
In the recreated module you seem to be missing some entity, see the error with the text no longer exists.
As this entity is not available the associations for the entity are also not available, thus the other errors.
It might be that the entity is available, but in the module you created. If so then replace the content in the microflows with the entity in your module and you’re all set.
Alternatively, download the module again so that the default module is created from the appstore and remove the other module.
