How to save API in my develop org with a double underscore

I just created an object based on the custom object and fields - when I try to save the API name as Trail___c, as described, it will not allow me to save the field with the double underscore.
API name of the object will be auto generated in salesforce with double underscore.

I had the same issue, I just created an object and the API did not have a double underscore.  I am trying to complete a Trailhead challenge  and I keep getting the error because it is not double underscore.

Did you ever get this resolved? I am having the exact same issue.

Justin, thanks for your response. As a matter of fact, I did get this resolved and I think the error code was misleading. The API name is auto-generated, but when I went back and revisited all of my entries, it looked like I had as typo which generated the error. The long underscore is actually a double underscore, just appears differently. Please feel free to contact me directly to discuss or if you are still stuck.

I had the same problem. What I didn't know is that "__c" is appended to what ever I enter for that field. Per the instructions, I was trying to create the field with "__c". 

I wasn't able to save the field when entered that way, so I did it with a single underscore. Of course, my work didn't pass the validation check. However, when I looked at the custom obejct, I noticed that the system had appended "__c" to my entry.

I went back and edited the fields and saved. This worked and allowed me to pass the validation.
