Having Trouble With Editing GR2 Animations

[armus 0]

Hello. I'm trying to make the male warrior character's arms straight in pc/general/wait and wait_1.gr2 animations using 3dsMax 8. I imported warrior_novice.gr2 as base, and then the wait animation. I rotated his arms as I want and saved it as gr2 again. the animation seems fine in the Granny Viewer app. But my character sinks underground during the wait animation in game. I noticed that in Granny Viewer the original wait animation is positioned high and rotated to 90° left. I couldn't get the animation I edited to be positioned as high as the original and I think this is the problem what buries my character underground when "wait" animation is active. How can i fix it? I'm adding images of my problem. I would be grateful for any help.
