Config is not saved, if changed over the HB-Config-Gui
Hey there, currently using following setup:

Homebridge Version v1.3.4
Homebridge Bravia Tvos  Version v5.0.1
Node.js Version v14.17.3
NPM Version v6.14.13

I can add new TVs using the wizzard, unfortunately, I can not add applications etc. using the GUI (I can select the in the GUI, after restarting HB these changes are not reflected in the config). Also if I open up the config after restarting, the previously added applications and settings are lost.

Here's my current config:
