This isn’t normal behaviour. However, I can only imagine how tedious.
The only reason I can think of for something like this. is that your Linux (Manjaro) system does not have write permissions to be able to save the configuration.
Which begs two questions:
- How did you install your system(s): and
- on what file systems is it installed?
So it should be kind of obvious that more information is necessary. To that end, please see:
Please also note and heed: Forum Rules - Manjaro
Hope you manage!
Tip: 
To provide terminal output, copy the text you wish to share, and paste it here, surrounded by three (3) backticks, a.k.a grave accents. Like this:
```
pasted text
```
Or three (3) tilde signs, like this:
~~~
pasted text
~~~
This will just cause it to be rendered like this:
Portaest sed
elementum
cursus nisl nisi
hendrerit ac quis
sit
adipiscing
tortor sit leo commodo.
Instead of like this:
Portaest sed elementum cursus nisl nisi hendrerit ac quis sit adipiscing tortor sit leo commodo.
Alternatively, paste the text you wish to format as terminal output, select all pasted text, and click the </> button on the taskbar. This will indent the whole pasted section with one TAB, causing it to render the same way as described above.
Thereby improving legibility and making it much easier for those trying to be of assistance.

Additionally
If your language isn’t English, please prepend any and all terminal commands with LC_ALL=C
. For example:
LC_ALL=C bluetoothctl
This will just cause the terminal output to be in English, making it easier to understand and debug.
Please edit your post accordingly.
