Removing the ">" inside the selection at the bottom changes where the second selection appears.
Thanks in advance, this is a real help.
See topic "Selection Highlighting"
"Wilfred Godfrey" 2013-02-17, you say « Note that the problem isn't the same-word-highlighting, but the second text selection near the bottom », but what your screenshot shows is actually a 11-line text in Notepad++ with 5 occurrences of the word "build_y" of which 1 selected and 4 also highlighted (NPPP > Settings > Preferences > MISC > Smart Highlighting). Unfortunately the default outlining in NPPP is the same for "selected" and "smart-highlighted", which got you (as me) mislead.
To remove any confusion: "NPPP > Settings > Style Configurator > Language: Global Styles, Style: Selected text colour > Colour Style > Background color", click the square (initially somewhat gray) and chose the bright vivid green square (which is #00ff00, i.e. "lime"). For details, go to topic "Selection Highlighting" then Ctrl+F "Style Configurator" (and don't mind the pollution that shows whatever, however, whenever, wherever I post).
