The config.cfg I modified is not maintained.

Using a locus map always gives me joy.
I was using a modified part of the config.cfg of the Locus Map Classic.

Today, I found that the config.cfg I modified is not being applied.
So I modified the config.cfg file again and ran the app, and the part I modified was applied well.
However, when I shut down the app and re-run it, the modified part was not applied.

I looked up the cause and found that config.cfg was automatically reinstalled and the existing config.cfg was deleted.
Why isn't config.cfg maintained?

Please modify the app so that the config.cfg modified by the user is maintained.
Thank you.

P.S.)
I added the contents below.
