Automation Error based on Rules

Hello,

I keep getting an error in a validation, I know what the error is but I don't understand where the error is getting derived from.
I am able to perform the same updates manually without error but am unable to have the same update run automatically with automation. I disabled the table rules and the change is made without issues. I don't understand why I am able to make the same update without error while the automation errors out. 
Thank you in advance!
