Not doubting that some have found this a little confusing as they have said they have found it so, but for myself I assumed "All" meant All without exception and anything else in the setup preferences (wherever those may happen to be) were overridden. This was so with Sigil also, insofar as direction was concerned.

I think Kovid is correct in what he is saying in that if it were not to be "All" then it would have to be "Some" (which would likely add other confusion), especially as the Oxford English Dictionary states for ALL "The entire or unabated amount or quantity of; the whole extent, substance, or compass of; the whole." so everything without any exception.

However, it may be that into other languages the regular translation of "All" is to a word that does not have that same strict without exceptions sense and that may be contributing to the confusion. I am no linguist but I think "toute" in French, for example, can have the usages of "many", "any", etc. as well as "all".
