Re-Arm, Refuel and Repair is missing because of the following reasons:
1. These facilities seem to be always available, I have yet to see a station that does not allow it, even if said facility is not listed on the system map.
It is not clear how these are used, or how these would be useful for external tools.
2. Other data sources I'm aware of don't use or list these either.
3. Reduce clutter (TBH these were in for a short time, until we've realized points 1 and 2).
Distance has always been there in the data from the very beginning, either you remember incorrectly or the field was accidentally omitted from the output earlier.
Btw, sometimes I just make screenshot(s) of the LHS panel and enter the distance later. Or check the distance after docking. That is unusual, and I do it only if there is no distance data yet, because both for trading and route planning it might be useful to have one roughly correct distance than none, even if it is not precise.
