The anomalously bright exposures 57 and 88 for the Mg VII 280.75 and Fe XV 284.16 windows are probably due to the fact that exposure times of 0 have been assigned to these exposures. When the intensity is computed, a division by the exposure time is performed. It seems likely that an arbitrarily small exposure time has been used giving a much higher intensity value than normal.

The image below shows an image from the Mg VII 280.75 window, with the two bright exposures clearly seen.

Only two windows show 'weird' spectra. Examples from exposure 26 are shown below:
