After Omega upgrade, IPTV simple client duplicates group on multiple instances


I was using Kodi with two different IPTV providers configured as two different instances (each one with its EPG and m3u file).  Each instance has their own groups, and I use same group name in two different instance to add channels from the two instance to a same group.

For example instance IPTV A has channel A in group CINEMA
Instance IPTV B has channel B in group CINEMA

After importing, I want a single group called CINEMA that contains Channel A and Channel B.

This was working as expected , but after upgrade to omega, the group cinema is duplicated, one group contains Channel A and the other group contains Channel B.

What is wrong? What happened?

Thank you very much.
