Saved has been clicked in INDI after and the .indi directory is owned by stellarmate user (not root). The two XML files are attached and the labels are saved in it.
Saving and loading the config for the ASI-EFW works fine for me. (7x36mm)
In you log I can not see that a config load is triggered.
Can you try to load the config via INDI Control Panel? ASI-EFW -> Options -> Configuration -> Load
Can you check what the setting in Kstars is? Settings -> Konfigure KStars -> Ekos -> General -> Configuartion -> Load Device Configuration - "On Connection"
