P3F Modding: Menu's blue background lost whenever tmx files replaced

(The "use skill on whom" menu still has the back ground though). I tried with another pak file - CAMP_SYS (only that one's tmx replaced) and it works fine so I figure CAMP_ALL is faulty. I tried "replacing" .tmx files with unmodified original ones (aka themselves), but the glitch still happens. Take a look at it:
