Linux, ARM64

### Installation

Custom package (OpenWrt, HomeAssistant, etc; please mention in the description)

### Setup

On one machine

### AdGuard Home version

v0.107.44

### Action

Running AGH on openwrt snapshot (13.02.23) 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 result

Expected result is that Encryption and DNS parallel request would be saved and not lost after logging in and out.

### Actual result

After logging out and logging back in :
