Please help: Reverse for 'all_clients' with keyword arguments '{'client_id': 3}' not found. 1 pattern(s) tried: ['clients/all_clients/$']

I am new to django and I am having trouble implementing the edit template to my project. I am encountering the following error:

Reverse for 'all_clients' with keyword arguments '{'client_id': 3}' not found. 1 pattern(s) tried: ['clients/all_clients/$']

I have looked on the site for similar occurrences such as Reverse for 'plan_edit' with keyword arguments

but I haven't been able to pin point the issue. I believe the issue arises when I add a hyperlink to my all_clients.html template. Also, the template pages for /clients/edit_client/?/ will load, however after submission using the save changes button the NoReserse Match error resurfaces as it attempts to load the clients/all_clients page.

Any help on this matter would be greatly appreciated. See code below:
