Extract a file with the same name change the file type

[Tasos]

When you have two files in the same folder with the same name like the following example:

1) Filenametest.xls
2) Filenametest.zip

And you try to extract the second one on the same folder, it change the name of the file with the wrong way and change the type of the file. For example, if I extract the file of the example, it will change it to "filenametest.zip (2)" instead of "filenametest (2).zip". It puts the counter after the file type.

Confirmed, added video to be clearer.

Final Result should be "Filenametest (2).xls", but the one returned is "Filenametest.xls (2)".
