NOTAM source data

Which source does VFRnav use when displaying the NOTAMs?

Specifically, this concerns the NOTAMs currently shown for EDRP; in VFRnav I get the notice that the airfield is closed; however on the DFS website I do not get this notice, which is correct.

Hard copies can be provided upon request.

@Strohmd,

thanks for the heads-up. A NOTAM with an incorrect closing time was issued by the responsible authority and immediately withdrawn. Our system did not record that correctly.
