If you created a filter in Google Analytics to block your own IP Traffic, you may notice new web properties you create in Google Analytics are not applied to this filter by default.
You will need to go into Admin -> All Filters and select the filter you setup for blocking traffic. You will notice other properties not applied to selected views. Simply add them to selected views and click save.
New Google Analytics Properties you create are not automatically added to customer filters you defined. You will need to remember to add them to your filters.
