parameter block

The underlined blocks are called autoblocks and show up as b in the PSD. You can get rid of them on a cue by cue basis or for the whole cuelist, depending on your situation.

For the whole cuelist: [Cue] 1 [/] {Autoblk Clean} [Enter]

thank you for responding.
 
I already tried the Autoblock Clean but it does not work. 
also there is no b in PSD

is there something wrong with Mark function or something? 

Try 13+14+16+17 color @ enter update

I'm not aware of a bug that would explain this. If you want to send us the showfile to eos(dot)moderator(at)etcconnect(dot)com we can take a look.
