Please help with some bugs.

I am using RM2K3 (yeah, I know) to make a small game. I have encountered TONS of bugs I googled and since RM2K3 is outdated there is no one to look to.

First bug:

When I go into battle, I have this "row" thing. It makes a noise when I try to hit it and nothing happens. Weird, but not too bad.

Second bug:

This one gets complex. When I hit "Fight", I have 5 Blank enemies with no names (which I tested, and, are actually real enemies with the same stats as the only monster I made, "Zombie". They are killable and have no appearance. Their names are blank). THEN the actual monster with an appearance. Weird. I don't want to kill 5 extra enemies when the hero is supposed to barely live an attack of ONE or TWO of them.

Third bug:
I have one hero, and I know this MUST be causing this. When I lose, it says "You lose!" as I set it to, and my character has the unedited Death condition, although I deleted all the other conditions. I don't get gameover. I'm on the field with Death condition and 0 health. If I go into battle, I just lose instantly.

TL;DR: I have bugs. I worked really hard on the game. I need them fixed. I don't know how to fix them. The game is pointless and stupid with these bugs.

Thanks in advance!
