If you load a cache with corrected coordiantes from a pocket query, you don´t see that they are corrected.
This is because there is no information in the gpx file, that these coordinates are corrected ones. In gpx files the original coordinates will only be overwritten with the corrected coordinates.
In gpx files from GSAK and iCaching there is a information about the original coordinates included. So Looking4Cache recognizes that the coordinates are corrected.
You can refresh the whole list (using the ‘All Data’ option) to see which geocaches have corrected coordinates.
