This issue was marked as CAN-17742 and was reported as having been fixed/closed. However, all current tests show that the issue still exists via upgrades and the behavior is in direct contrast to Cubase documentation as to the intended result.
CUBASE 9/10 Help Documentation
You can cut or copy and paste selection ranges, using the functions on the Edit menu…Pastes the clipboard data to the start position and track of the current selection. Existing events on the tracks remain at their original position.
In Cubase 9 this feature worked.
However, since Cubase 9.5 was released this behavior has changed and a bug introduced whereas selecting and copying any audio region in the Editor and moving the selected area to any other location within the audio Editor to paste the content causes all audio content events in the track to shift to the right. They do not remain at their original position. The events are shifted.
- Import or record audio to an audio track
- Double-click the audio track to access the editor
- Select a region of audio
- Copy the content (Edit -> Copy)
- Click and hold the selected region and move it to another location within the audio
- Paste the audio content at the new location (Edit -> Paste)
The content is pasted within the selected region but all audio content to the right of the region is shifted to the right making all previously synced audio out of sync with the project. So all audio events to the right of the pasted region do not retain their original position. The pasted region affects all audio event content to the right.

Issue is reproducible without any plugins or 3rd party components and has been affirmed via the forum by many other users.
In Cubase version 9 and prior, the content pasted within the region would be pasted at the start position and track of the current selection and existing events on the tracks remained at their original position per the expected behavior.
