insert and overwrite sequences button not working on laptop.

So I have just automatically synced a multi cam sequence to some audio tracks using the create multicam source sequence button and when I went to drag that sequence to my timeline with the insert and overwrite sequences unchecked to reveal the original clips, I couldn’t get this to work. For some reason my laptop just wont show the original clips no matter if insert and overwrite sequences is highlighted or not, its like this button isn’t working. So I tried an older version of premiere, maybe something has changed in the new update but nope, still not working. I then remoted into my desktop pc to try it on there, its running the same older version as my laptop and yep, worked just as expected, I’m not sure what’s going on and any help would be appreciated, how it works on my desktop but not on my laptop, not even in the new version. I’ve attached a video to better showcase my issue.

i have reset preferences and workspaces to see if this helps but it hasn’t
