ZF7363 is a legacy 802.11n platform and support for them in the ZoneDirector firmware code will have stopped quite some time ago.
Similarly the ZD1100 platform is also legacy and end-of-life and firmware support has stopped.
You can find release notes detailing the final supported versions for both platforms on the Ruckus Support site: https://support.ruckuswireless.com/
At a glance, it looks like the final version of code supporting ZD1100 is 18.104.22.168.84. And final version supporting ZF7363 is 22.214.171.124.134.
I would recommend a complete network refresh, potentially with a Ruckus Cloud or Unleashed controller platform and R550 access points.
I hope the above helps,
