instead with the male character everithing work but the program take red's animation at the begin of the battle (i have modified the main characters)

i check the metadata file but everything is ok, maybe are the trback image that i had substitute with the originals...
in essentials 17 everything worked, maybe i've lost some changes in regard... what should i do?
thanks in advance to who respond me :)
