I spoke to JP at TAA and he rembers a similar event some years back. It's something to do with Jepp being US based and there being no class A in the US except for airways. Since we don't want airways on VFR data then all class A gets omitted. Garmin has some kind of work-round for it but my unit is not a Garmin.
It's frustrating that I have to extract this information from other users rather than getting it direct from Jepp. Customer service at Jepp is non-existant but obviously I need a fix from them somehow.
