5e Shaped Companion Script

I am having a rough time importing stat blocks. I tried everything I can think of to get it right but wish there were an easier way or some sort of template to import monsters. I was trying vampiric mists and no matter how I laid it our I always got an error. haped Scripts Error Error: Field armor class should have appeared 1 more times Field str should have appeared 1 more times Field dex should have appeared 1 more times Field con should have appeared 1 more times Field int should have appeared 1 more times Field wis should have appeared 1 more times Field cha should have appeared 1 more times

the newest on both of them, just had a hard time trying to get the statblocks setup it is not easy to do. I tried to copy from PDF and it would just mess up.
