images not in order after import sequence

I am trying to import a sequence of images. The names are NiklaPurpleKaya_000001.png to NiklaPurpleKaya_005628.png They are not imported in numerical order as I want. How do I fix this? Is the names to long?

It looks like this:

I also see that the Import Images is not highlighted after I mark the images I want to import. I marked the first image then highlighted the import sequence then use shift and select the last image I want.
