Sorting look fine.. Look like you have natural sorting enable
With natural sorting it will make sure that number in the file name are sorted before letters.
And you got filenames starting with 6, then 27, then 64, 85, 120 , 160 , 10894, 100873, 100874
You can disable it in
Menu > Configuration > Explorer Panel Settings > Display (Tab)
Scroll down to the "Sorting and Columns" section and disable "Sort files and folders in natural order"
