I would like to say the following in German:
Unfortunately, we could not reproduce the Save-as-XML issue that you are experiencing on your computer.
but I cannot find a word other than "Problem" or "Fehler", which is too negative:
Leider konnten wir das Save-as-XML Problem nicht reproduzieren, das bei Ihnen auftritt.
Is there a word in German which has the same meaning as "issue" here, i.e. something that could be a "problem" but could also be something for more neutral, even positive?
