Yea, that sounds like the problem, your console thinks it's PAL. Have you tried redoing the initial mod, so you can select the proper fw? Once the console is modded, it will let you update the sys menu without removing the mods, so Im thinking an official Nin10do update to wipe everything clean or retry the mod from the beginning so you can change it from a PAL fw to NTSC. I dont use anytitledeleter so I cant give a heap of info on that, usually if I screw something up I just redo my mod to start fresh, its lengthy but its worth being done right.
*since your HBC works, you may be able to use anyregionchanger to change your consoles video without having to redo everything.
