ghost traffic target

I have an IFD540, AXP340, EX600 and I just had a Skytrax100 installed.  I believe the Aspen 1000 Pro is the pressure altitude source for all of this.  I am now getting a ghost traffic return on everything (panel mount as well as my Stratus/iPad) at my altitude and distance (0 ft and 0 miles).  This comes and goes but it is quite annoying because it causes continual traffic alerts.  The ghost target is usually 0 feet away but sometimes it is as much as +/-200 feet.  Does anyone know what causes this and what can be done to prevent it?  Previously with just the AXP340 for ADS-B out and the Stratus/iPad I was not getting these ghost targets.

There are possibly some configuration settings that could be causing this, however, if you are flying in the TX, AR and MS areas (to name a few), we have heard that the FAA had some issues where they were sending TIS-B information to ADS-B Out Aircraft. The FAA has also created a form to log these events so they can reset whatever equipment might be causing the error (https://docs.google.com/forms/d/1M5Gb0X54OHntMw_nYSZVxo1xgxIK-ymdyCxHwsX9Hcg/viewform?c=0&w=1)
