Describe the bug
After setting up OSPV3 (IPv6), check the Routing Table at Routing > Diagnostics > OSPFv3 > Routes - nothing is displayed. If I check it via Routing > Diagnostics > General > IPv6 Routes - all IPv6 Routes included all OPSFv3 loaded rules are displayed. Additionally checked with show ipv6 routes ospfv3 at vtysh - all routes are shown.

To Reproduce

1. Set Up OSPFv3 in a manner to import routes from another OSPFv3-Instance
2. Click on Routing > Diagnostics > OSPFv3
3. Open tab Routing - no routes are shown

Expected behavior
Show OSPFv3 imported routes at the given point like it's done with OSPF

What is the output of:

configctl quagga diagnostics ospfv3_route

plugins/net/frr/src/opnsense/service/conf/actions.d/actions_quagga.conf

Lines 173 to 178 in a6acffd

	[diagnostics.ospfv3_route]
	command:/usr/local/bin/vtysh
	parameters: -c 'show ipv6 ospf6 route %s'
	errors:no
	type:script_output
	message:FRR diagnostics "show ipv6 ospf6 route %s"

We only added errors:no there recently, so I assume the output is malformed or empty in some way.
You can try removing that in the above file if it makes a difference, but then we have to see the exact difference.
If you change actions you have to do service configd restart afterwards.
