Concurrent Programming Question

I have a Hurco KM3 Ultimax 11 That has run fine for 23 years.
I never ventured into Concurrent programming until last week.
Now I can't get out of it.
Previously I would stop the program and edit it and then return it to "auto"

Now it seems I have two programs at the que, even though I only want one
In other words, Ultimax will not let me edit a stopped program, I have to switch it out of "running" and into "programing, and then switch it back, else it runs another program in "auto"

Both my manuals, tell me how to get into concurrent, but not how to stop the joint programs from being up at the same time

Thanks
Rich
