Problems displaying a custom range of images from stack

In an image sequence of dicoms from a CT scan, I am trying to open a specific increment of 300 images from a full sequence of 1280 images. In the sequence options box I select 300 as the number of images and 575 as the starting image. But when the sequence opens it always starts near the beginning of the sequence, on about the 50th image instead of the 575th. This is in ImageJ not FIJI. Appreciate any input.

It works as expected for me when I open 300 images starting at 575 from a sequence of 1280 created using the FIle>New>Hyperstack command.
