I've several virtual GPS instances in my list. Some are mine and some are shared from other persons here (visible by the add of '(shared by ...)' as the list's name.
Because these lists contains (mystery) caches with real corrected coordinates and some to solve and therefore without such data, I tried to search for them through the "glass" below the matrix table.
I try with "corrected latitude" with different settings in the selection, but no one works.
First I thought that this might be a problem of the selected UI language, but the behaviour is the same on the english UI.
