Corgi Engine Melee Attack Animation for original character won't transition

I have been experimenting with the corgi engine for a few months now and have been stuck for a few weeks on getting my "Melee Attack" animations to trigger during gameplay. I have created and used several prefabs provided in the engine ( Retro Corgi, Pixel Corgi, Rectangle ) and have equipped them with the provided weapons as well as creating my own melee weapon models for these characters based on the video tutorials, Documentation and the forum. I have created a playable character that idles, runs and jumps based on the character abilities of the engine and created parameters that coincide with the "Rectangle" character that is recommended for development and all of those animations and abilities function flawlessly... but my melee attack animation won't play.

There appears to be only one "condition" necessary to make the animation trigger the way it does in the prefabs "RectangleMeleeAttackStart". I have tried that parameter as a condition on several models trying to start from scratch. I have also tried using the condition "MeleeAttack" duplicating the parameters and conditions of the "Retro Adventure Corgi" without any success. I have double checked my spelling and Any help or advice would be greatly appreciated.
