Wireguard Add Client: config not downloadable

I'm adding a WG client via Web-UI in the WG server management.
The "Configuration" column shows a document icon but I can't download the config file for the new client and I have no way to see and export the config data.

(Router: GL-AR150, latest FW: 3.216)

and hints?

Hi,

  1. Please provide some screenshots to describe the situation.

  2. Please try changing your browser.

This AR150 can display the QR code and content of the WG profile on my side.
