Kodi addon download/update issues

I am using KODI 17.3 version on my Andorid TV box.

1. When i try to install Fusion Addon, I have entered http://fusion.tvaddons.ag as the source.

Select SYSTEM
Select Add-Ons
Select Install from zip file
Select fusion

When I try to “install from zip file” the list is empty (see attached pic) the list is empty. “kodi-repos” is missing.

2. When I tried to update some packages, it is showing the 0% then again showing “Update Available” message. On the lower right hand corner it flashes a message “Update failed” and to see the logs.

Live streams are working. Also the box is is getting dynamic ip from the router.

What could be wrong. How can I update various KODI addons like ZEM as it is bit old and many live tv streams are not working.
