Opened files create new window

I’m a sumatra pdf user of version 3.2 for win10. When I open a opened file using sumatra, it create a new window instead of the window opened before, which means that I will get two SAME window of one file.And this problem doesn’t happening on the last version 3.1.2. Looking at the picture below for details.

On re-testing with a fresh session all versions will open two tabs for one file unless called externally
