Welcome to the forum! There is an additional step for a Wayspot to become a pokestop. See this topic: Why an accepted Wayspot may not be used in Pokemon Go (S2 cells and Pokemon Go)
I will see if I can find your Wayspot to illustrate the issue.
If you have only had one accept in that many submissions, you may want to post for advice in Nomination Support
Edit: found it. Wolf Creek Park Picnic Area #2 is already in game in this cell, so yours cannot be a Pokestop or gym.
It does appear to be eligible to be used as a Power Spot, but we have not confirmed how those are chosen yet.
