I understand your frustration, but clearly Niantic has made a decision.
In my thread here I had a similar issue with one trail marker
Generic Business Rejection from Niantic Voting For Trail Markers
Now they did go back and approve one, but the other they did not. I even appealed it and it is just generic to them so they refused it. Apparently it has to have a name, or maybe a decision point, or distance, etc. Technically all my markers in this area except for one which is on a named trail would be needing to be removed then. 
Perhaps if more questions pop up this will be more clearly defined.
Don’t waste your nominations on ones like this. I know not to nominate anymore when I am out there unless I have lots available, which I usually don’t.
