Does it save if you try select 2.4ghz checkbox on all 4 ssid's

As @ww said, it looks like you are trying to save a config with no bands for SSID2.

It appears to want something selected even for the disabled SSIDs. So, just check any of the boxes for SSIDs 2-4 and it should save. They're disabled so it doesn't matter anyway.
