Hi,
This seems to be strange.
I tried doing this again on my PC. I found no issues.
![Static Routes.PNG Static Routes.PNG](https://community.meraki.com/t5/image/serverpage/image-id/5293iEEEC4823AC9DAF4A/image-size/large?v=v2&px=999)
How about making sure about the following.
1. Create 1 Route at a Time. Save Changes. Refresh the page and try adding new Route.
2. Make sure while creating new route no check boxes are selected under Static Route.
3. Try using another browser / incognito mode of the browser.
Hope this helps.
Regards,
Ajit
