When you are in application design mode and you want the changes in your DocTypes, Reports etc to affect the app repository, you must be in Developer Mode.

To enable developer mode, update the site_config.json file of your site in the sites folder for example:

frappe-bench/sites/site1/site_config.json

Add this to the JSON object

"developer_mode": 1

After setting developer mode, clear the cache:

$ bench frappe --clear_cache
