Journal dropping line(s) after it has been posted

Hi,

I'm wondering to see if there could potentially be any reason why an online journal posted once correctly later shows that a line is missing and journal is not in balance any longer. Below is a partial (bottom portion) of the Lines tab:

Same journal ID appears in the search but with another date (one week later) with approval status as 'denied". Trying to figure out what might have happened in case you have come across similar question/scenario.

Thank you,

Armand
