I think it's important to understand precisely what you wish to accomplish with your new modifiers. Looking at the commented out portions of your file, you appear to have tried to replicate the passive Great General Effect for combat strength and movement. I'm assuming the flanking and support AOE bonuses are supposed to be similar. What isn't clear to me, though, is what you're trying to do which isn't working for you.
Since I'm kind of poking in the dark, I compared things in the base game to what you have. I noted the base game uses either true or false for ActionRequiresOwnedTile in every instance in which it exists in the XML files. You've got a 0 for yours on Line 61. The same applies to ActionEffectTileHighlighting later on Line 63. I'd set both of those entries to false instead since the game is almost certainly looking for that instead of a 0.
While this is likely fine so long as it is consistent, there is a typo in ABILITY_THONG_CHE_AOE_FLAKING which you may want to correct. I assume that's supposed to be ABILITY_THONG_CHE_AOE_FLANKING since later on it's associated with GREATPERSON_THONG_CHE_FLANKING_AOE_LAND. It can't hurt to correct since typos tend to go sideways later on if we're not careful. I ran into something similar myself where I switched a couple characters when typing a common word in my own mod. Tracking that down took way longer than it should have since I wasn't looking for a typo.
Anyhow, I'll leave things there since anything else is making too many assumptions about what you may want to be doing.
