You need to post what type of files you are looking for, what scan modes have you tried, which file types aren't maching, etc.

You need to filter to your selection.

Select (highlight) the files and then right-click and select 'Filter to selected files'.
You should now see that the Selection Assistant only works on that filtered selection.

It's already there - you can uncheck the option 'Don't follow NTFS mountpoints and junctions' on the Scan Location tab.

"Group sizes" filters by the total file size of the group

Which Selection Assistant function are you using to mark?

Are you sure you are using the 'File sizes between..size' filter and not the 'Groups between...size' filter?

Those are false positives, you should be fine to install.
