About the Filter Bar drop-down

According to the manual:
"The drop-down attached to the filter field provides a quick way to filter on the various file types that are actually present in the current folder."
Why doesn't it follow the current state of the folder instead of the actually present in the current folder?

For example: I use Advanced Selection dialog to select the items created within 1 month, the other items don't match are hidden but the drop-down keeps showing the content of the folder (extension, file counter) instead of the items created within 1 month (the current state of the folder). The Filter Bar works on the current state of the folder but the drop-down does not.

This is just my thought, what do you think, guys? Thanks!

That´s because it is not intended to work like that, i would say. The file count info is independent from the label filtering. But you can filter or sort by the labels, of course.
