If a job is a "Paid Job" as noted in the Job section of the Map Detail page it will not have our logo in it. Paid Jobs will either have no logo or the one that you define for your custom branding. If a job is not paid, it will have our logo on it.

A "Paid" job is a job created with purchase points. A non-paid job is one created with promotional points (the free points associated with the account at signup).
Promotional points are converted to Purchased points at the time of any purchase so if you want to covert your point balance to Purchased points to be eligible for custom branding you will need to make a purchase.
