Currently files are sorted alphabetically before importing. This means that if your files have names which have the minimum number of digits, Ej. 1,2,3,4,5,6,7,8,9,10, then the list will be sorted as 1,10,2,3,4,5,6,7,8,9. That happens because the names of the files are seen as strings of characters, rather than numbers.
I can add the option to choose between different sorting modes to the configuration file, but until I do that you can resort to naming your files in a way they will be sorted correctly every time. One way would be padding the names with zeroes Ej. 001,002,003,004,005,006,009,010
That will make sure the alphabetical sorting sorts the numbers as expected.
