Removing "Bug" and coping bug

What is your operating system?
Windows 10

What is your Shotcut version (see Help > About Shotcut)? Is it 32-bit?
20.04.12 64bit

Can you repeat the problem? If so, what are the steps?
(Please be specific and use the names as seen in Shotcut, preferably English. Include a screenshot or screen recording if you can. Also, you can attach logs from either View > Application Log or right-click a job and choose View Log.)
There are two probelms. I have been using shotcut for a couple years now. It now seems that clicking remove on empty space impacts ALL tracks not just the one that you are clicking on. Is there a way to fix this? Second, when I copy and paste anything on a higher layer, everything below it gets deleted. Thank you, this program is amazing as this is the first issue that I have had ever with it.

You haven’t explained the steps to repeat the problem. You’re going to have to detail the steps to repeat the problem just like the question asks you in order for this to be a useful bug report.

Ripple edits across all tracks is probably on. If so, turn it off.
