Bei mir Karte Niedersachsen, Server1. Gleiche Phänomen wie bei Carsten.

You must update your GCDroid to the newest version, then gpx export ist possible.

Made a new test, with a cache I never found, because it was archived, before I started caching.
So this cache is not in any db I have in GCDroid.
It is GCH82M and I can load it, over the search funktion.
Its now in the @search db :-)

Hmm, I searched for this GCCode, in the search field on the first side, where i also can search for name or adress

For me archived cache are shown.
Just tested ist with a cache, which was archived 2009.

GC1PTAH

Den Vorschlag hat schon jemand gemacht, ich sag mal nicht wer. :-) :-)

Umsetzung ist in Arbeit.

Use the filter function to find it.

Problem ist gelöst, bei beiden Geräten. :-)
Kann geschlossen werden. 

I have never seen a cache from my ignore list, on the Live map.

Maybe it was a false alarm and an offline db was used, where caches from the ignore list were included.

Can be closed, problem is solved with V2.0.4-RC1.
Same problem was discussed at Facebook.
