In multi mode virus says part is off but sounds

Hi, if you use your Virus with a midi cable in multi mode, please help me out!

I use the Virus in multi mode in order to save per song 16 parts on the virus. Some of the parts are set "Part Enable: Off" to prevent the virus to make sound on selected midi channels. But they are soundig although the screen shows that the concerning part is "Part Enable: Off". Virus OS is 5.1.1.0

This problem occurs after saving the multi mode patch on RAM Patch no. 2 after pluging out the powercable after going to sleep mode.

Does somebody know how the solve that issue?

Thank you! Sammy

The issue still happens! So when I take the Virus to a gig i have to turn on/off again each part to setup!
