SPM requires the specification of the volume indices when you input the data. You've essentially just selected the first frame of the 4d volume. When using the spm_select dialogue box, change the filter from 1 to 1:number_of_total_volumes (so if you had 300 timepoints, it would be 1:300), and then select all images that pass the filter.
