ghost traffic target

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)

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.
