SSIDs won't enable

Installing and Using OpenWrt
1

Hi, I'm a total noob, so please excuse my ignorance. I'm having trouble getting additional SSIDs to enable for my Guest and IoT networks. The 5 GHz Guest works great, but the others just refuse to come up and they are configured identically. I ran iw phy phy0 info and I think I have the VAPs to be able to run these additional SSIDs:

valid interface combinations:
* #{ managed } <= 16, #{ AP, mesh point } <= 16, #{ IBSS } <= 1,
total <= 16, #channels <= 1, STA/AP BI must match, radar detect widths: { 20 MHz (no HT), 20 MHz, 40 MHz, 80 MHz, 80+80 MHz, 160 MHz }

Anything else I should be looking for?

I am running on a Linksys EA6350v3
OpenWrt 19.07.2 r10947-65030d81f3 / LuCI openwrt-19.07 branch git-20.057.55219-13dd17f

Post the broken config (/etc/config/wireless) in full, minus passwords.

Sure, here you go:

config wifi-device 'radio0'
        option type 'mac80211'
        option hwmode '11g'
        option path 'platform/soc/a000000.wifi'
        option htmode 'HT20'
        option channel 'auto'

config wifi-iface 'default_radio0'
        option device 'radio0'
        option network 'lan'
        option mode 'ap'
        option key ''
        option ssid 'Linksys00801'
        option encryption 'psk2'

config wifi-device 'radio1'
        option type 'mac80211'
        option hwmode '11a'

        option htmode 'VHT80'
        option channel 'auto'

config wifi-iface 'default_radio1'
        option device 'radio1'
        option network 'lan'

        option device 'radio0'
        option mode 'ap'
        option ssid 'Linksys00801_Guest'
        option key ''
        option isolate '1'
        option encryption 'psk2'

        option mode 'ap'
        option network 'VLAN20_IOT'
        option key ''
        option isolate '1'

Try to set channels to some fixed values like 1 and 36 that clearly don't need DFS. Also, set the country code on all SSIDs.

Another reason for AP not enabling itself can be that support for 802.11b rates is not disabled.
