The www key labels produce wrong behavior on the output eep file

[anjari]

I have KBP V60 Type R keyboard and I'm trying to map key combination FN + U/J to "wwwback" and "wwwforward" respectively:

[{a:2},"Esc\n\n\n\n~\n`",{a:4},"!\n1\n\n\nF1","@\n2\n\n\nF2","#\n3\n\n\nF3","$\n4\n\n\nF4","%\n5\n\n\nF5","^\n6\n\n\nF6","&\n7\n\n\nF7","*\n8\n\n\nF8","(\n9\n\n\nF9",")\n0\n\n\nF10","_\n-\n\n\nF11","+\n=\n\n\nF12",{w:2},"Backspace\n\n\n\nDelete"],
[{w:1.5},"Tab","Q","W\n\n\n\nUp","E\n\n\n\nFn4","R\n\n\n\nFn5","T\n\n\n\nFn7","Y\n\n\n\nFn9","U\n\n\n\nwwwback","I\n\n\n\nPrtsc","O\n\n\n\nScrlk","P\n\n\n\nPause","{\n[\n\n\nUp","}\n]",{w:1.5},"|\n\\\n\n\nInsert"],
[{w:1.75},"Caps Lock","A\n\n\n\nLeft","S\n\n\n\nDown","D\n\n\n\nRight","F\n\n\n\nFn6","G\n\n\n\nFn8","H\n\n\n\nFn10","J\n\n\n\nwwwforward","K\n\n\n\nHome","L\n\n\n\nPgup",":\n;\n\n\nLeft","\"\n'\n\n\nRight",{w:2.25},"Enter"],
[{w:2.25},"LShift","Z\n\n\n\nFn2","X\n\n\n\nFn1","C\n\n\n\nFn3","V","B\n\n\n\nVoldn","N\n\n\n\nVolup","M\n\n\n\nMute","<\n,\n\n\nEnd",">\n.\n\n\nPgdn","?\n/\n\n\nDown",{w:2.75},"RShift"],
[{w:1.25},"LCtrl",{w:1.25},"LWin",{w:1.25},"LAlt",{w:6.25},"Space",{w:1.25},"Fn0",{w:1.25},"RWin",{w:1.25},"Menu",{w:1.25},"RCtrl"]

After I flashed the keyboard, I found out the "wwwback" function doesn't work and "wwwforward" produces browser refresh behavior instead.

I did some experiments with other www key labels and I found out the www key labes don't produce the function correctly in the ep file, their behaviors somehow get swapped each other, e.g. the "wwwhome" and "wwwback" labels produce www back & forward behavior instead.
