Cubase 14 - copy - paste

Hi. Has anyone noticed that copy/ paste doesn’t work if you’re copying midi from the new drum machine track to another midi or instrument track. It works as usual on all other track types apart from the drum machine track (obviously not in pattern mode).
Also, my automation is very hit and miss. Sometimes it doesn’t write and sometimes it writes but doesn’t read. Sometimes it’s fine. I have been using Cubase for many years and I’m pretty sure it’s not user error.

Any thoughts about either of the above would be great. Cheers. Jon.
