Perhaps not configured. Also it's not recommended to send RA's with
prefix length 48...

Looks like this is a routing/prefix issue.
In your case you have to use /48 to the ISP's network.
Dig into routing and proper prefix length usage.
To split the /48 into /64's you'll need a second router on your site.
ISP - /48 -> your router - /64 -> LAN1
+- /64 -> LAN2
...
BTW: would be good if your ISP route the assigned /48 either via an
unnumbered or a P-t-P numbered tunnel (different addresses than /48)
to you.
