Resharper automatically removes whitespace on run

I've been facing a weird problem in Resharper recently. When I make any bit of change on code and run, the whitespace after where the cursor is currently at are removed.

Here is an example:

public void Sample() 
{
    Console.WriteLine("Resharper");
}

Just assume that the mouse cursor is placed at the 3rd line after the semicolon. When I click 'Run', the code instantly gets reformatted and becomes like this:

public void Sample() 
{
    Console.WriteLine("Resharper");}

I could not find anything in Options. I believe that this is not a formatting issue because, in the options panel, there is no setting indicating how to apply formatting on run.

Do you have any advice?

(By the way, I am using a licensed Resharper Ultimate 2017.1 and Visual Studio 2017 Community)
