Far Plugin cant remember Overwrite Confirmation value

I suggest, it is a critical bug -- plugin overwrites user files without confirmations after restarting FAR.

Steps to reproduce bug:

1. Install FAR
2. Install WinSCP plugin for FAR, v.1.5.1
3. FAR: Go to F9 -> Options -> Plugins Cfg -> WinSCP -> Confirmations
4. Set overwrite confirmation EXPLICIT by:

[X] Overwriting of files (? = use FAR settings) <== "X" here

5. Press Enter
6. Restart FAR
7. FAR: Go to F9 -> Options -> Plugins Cfg -> WinSCP -> Confirmations

Now I see:
[ ] Overwriting of files (? = use FAR settings) <== WITHOUT X!

8. Plugin save option value for [?] and [_] correctly.

Thanks. I'll check it.

Is any results of investigation available?
Thank you.

Not yet, sorry :-(
