EWA Reporting gone wild after SPS13 on SolMan

Hello,

I am facing an annoying problem with the Solution Manager that I work with.

After there was a SPS upgrade from version 10 to  13, people are receiving EWA reports from systems that they were not configured for.

For example my email was configured to receive EWA reports for systems 1,2 and 3, and now  I receive EWA reports also  for  systems 4,5 and 6.

I removed my email from Solution Manager for EWA reports and I  still receive EWA reports for random systems.

Any thought for this?

First I though to remove all emails and reconfigure them,but if I  still receive EWA reports despite removing my email,it would be  pointless.

Please let me know your thoughts about this. Thank  you.
