Help with AOE2HD Scenario Editor???

Okay, so I've used the Scenario editor for years, hundreds of times. But this time when I went to make a map, all of the enemy units turned to have thousands and thousands of HP and attack, and also range.

I was just messing around, and I made 3 sets of my own units have SLIGHTLY higher speed, a tad more attack but added 5000HP to them on top of their usual HP. I made sure and double checked that my area selections were set to Player 1 (myself) and only the areas of units I wanted to modify, etc. I've done this a bazillion times. I figured maybe my triggers were glitching, so I disabled them temporarily to see if that helped. Nope, all of the enemy units spawn with thousands of HP, attack and range. None of it makes sense. What's worse is that even though the buildings and units show thousands of range, they don't seem to be able to attack me from further than usual. But their HP and attack are insane. I think the AI took out my 10k hp, 150 attack, 5 speed army in like 30 seconds.

Also one thing I find annoying is when you start on post imperial age and give them a decent chunk of resources, the AI seems to do nothing but spam castles and towers which is just llovely.

Anyway, can anyone help with this? I REALLY don't feel like having to remake the Scenario if I don't have to
