cubase 10.5

what is this ? am trying to cut in the drum track, but it only create more events ontop. see the strips and black. how do I get rid of this ?

select them and press delete and they will go away (unless they are locked)

Yes i know that. Maybe i didnt made myself clear. Why do they appear such way. Its hopless to splitt the event. When i use the splitt tool it creates more event on the track. Am not been avle to splitt it

it’s just multiple events. if you drag it to a new track it is easy to see what it contains. they show up (in my experience) if I drag 'n drop over the event already there, have the track armed for recording and similar things.
