VPN->IPSec->Tunnel Settings empty after adding Phase2

[Huanaw06]

We just added several Phase2 entries in config and now the whole page is empty.
However, Status Overview shows all Tunnels, also the last added. All of them are online.

But it is no longer possible to config them via GUI. In the config.xml I can see all Phase2 and they look OK.

What can I do, to see what is missing here during load of the Tunnel-Settings-Page, which makes it empty?
