Short-term internship visa issued by Austria – what to do if no work-related remark is present on sticker?

I recently got my Schengen short stay visa approved to travel to Austria for an internship for less than 90 days. However my comments / remark section on my visa sticker is just blank. No remarks. I expected to see something like “ERWERB” written on it to show ability to get gainful employment (due to my internship).

What should I do to ensure I can complete my internship?
