Video of the issue.

SUMMARY

I'm having an issue trying to copy and paste two clips (one audio and one video) from one point in the timeline to the other. Kdenlive says I don't have enough tracks to perform the action. Though there's plenty of space on all tracks! They're all active and unlocked. I have 7 video tracks and 7 audio tracks. But I can't seem to make it work unless I copy and paste the clips separately.

I used hold shift + left click and drag to select the clips, then ctrl + c then position the playhead where I want and then ctrl + v. It works if it's only video clips. But if there's one audio clip, it says that there are not enoughttracks.

Can you please add you full About info

Also can you reproduce this in a scaled down example (without so many tracks) ?
