Unable to save encryption settings on AGH

Running AGH on openwrt snapshot (13.02.24) on MT6000 router
I have 4 DoH in the Upstream DNS servers

I choose enable encryption and disable enable plain dns and save ( the save button doesnt seem to chnage after choosing save). But after logging in and out the tick is back on plain dns and untick in encryption option.

Expected is that Encryption would be saved and not lost after logging in and out. After logging out and back in the tick goes away from enable encryption and is back to enable plain DNS

I have tried resetting router and also done fresh install three times of AGH

What could be the problem. Any suggestions how to resolve?
