Check this configuration in the SSH after you change the config and click the 'Apply' button:
cat /etc/config/wireguard
Is the config displayed in WebUI same as the SSH configuration?
No.
In the GUI the edit window has a red-lined boarder and the Apply button shows a shade change when selected.
As the perms are 0775 and owned by root does the logged in user (admin?) have permission to write the edit?
Everything on the router runs as root, so that should not be a problem.
It seems that the UI check there are some parameter missing.
What port did you change to?
You can post screenshot with your private data marked.
The configs I edited are machine generated and already working.
I tried various edits. Add a space into a line, change the DNS name for the server or a port.
None are saved.
I understand. But if you can give details it will help to solve.
