WLAN removed from ZD but AP still retains it - oddity?

In response to info from another thread I'm trying to rationalise my numerous WLANs (from 12 down to circa 6).

24hrs ago merged 4 WLANs into 2 in doing so removed WLANs called YELLOW and BROWN.

However today while digging around on an AP noticed that it still retains the WLANs that were deleted.

ZD screnshot with my WLANs (note no YELLOW or BROWN).



AP screenshot showing the deleted WLAN still "known" by AP (even if not broadcasting.



and here's BROWN still showing up on AP



Haven't rebooted the AP - perhaps that will remove the extraneous WLAN entries.
Does this make sense? Is this a bug? Thoughts.

More info:
Upgraded ZD to 9.7.1.0. b17 (from 9.7.0.220) a few days ago.

ps: deleted posts due to realising the firmware numbering weirdness was due to AP retaining a back up image of old firmware. Just worked that out!

Now checking the AP from ZD gui...



So ZD thinks AP at different version than the AP reports directly.

Thinking there's a bug here (or I'm just missing something - always possible).

After rebooting the AP YELLOW and BROWN WLANs have gone.
So is that expected behaviour? A reboot of APs is required to clear dead WLANs.

Curious.
