The frontend servers being 2.2.12 is most likely your problem. The LSUB
is being proxied to the backend server since that's where the
subscription information is. Your 2.4.x backend will correctly list
mailboxes on remote servers as \Noselect. The 2.4.x frontends know how
to magically strip the \Noselect from the proxied response, but the
2.2.12 frontends don't.
You should upgrade your frontends to 2.4.6 first, but the other trick is
that you have to make sure you disable any capabilities that the old
2.2.12 backends don't support using the suppress_capabilities config
option in imapd.conf.
suppress_capabilities: ESEARCH QRESYNC WITHIN
