Class Descriptors File

I am having a really hard time getting a Class Descriptor table formatted properly so as not to prompt the dreaded Error: Invalid class descriptors header. I have tried what feels to be absolutely everything. Please help!!! (See the attached jpeg below of one of my many many formats....). I am using Fragstats v4.2.681 [64x] [built on 2023-04-21].

I have finally figured it out. I was creating my Class Descriptor file in Excel and saving as a CSV UTF-8 (Comma dilimited) (*.csv). Apparently this format creates an invisible Byte Order Mark at the beginning of the file. In the future, I will use the standard CSV (Comma Delimited) (*.csv) to avoid this frustrating road block.
