RA sends auto-generated ULA prefix in 24.1

Hi all. I implemented ISC DHCPv6 using a delegated prefix from the ISP. It generally works fine except for RAs containing a ULA prefix that is not defined anywhere in the GUI. This causes all clients to get a an address from the delegated prefix(via DHCPv6) and a second one from the ULA prefix (generated from the RA prefix). Is there any way to get rid of the ULA prefix? Is this intentional behavior or a bug?

If you did not set it up it comes from the ISP? I have no idea where it would be from otherwise.

That is the strange part - it's not defined anywhere and doesn't come from the ISP.

Did you check with ifconfig in a shell if the matching ULA is on any interface of OPNsense at all? Possibly some other device is sending the RAs?

Ignore this thread - the problem was on my end - I have 2 AppleTVs and they're both sending RAs with ULA prefixes.
