Only the first video is always rendered on the video track

Only the first video is always rendered on the video track, when I select the second clip from the video, it outputs the sound correctly from the second clip, but the video rendered the first one.
How can I fix this?

WaveLab is not a video editor. WaveLab renders video clips per clip.

I know that wavelab is not a video editor.But if I have several video clips and I need to replace the sound in each one, I think it’s not difficult to implement it, or am I wrong?
It also says the “range of the active video clip”, I select the active video clip and renders the first video clip of the one I need.

Excuse me, I didn’t really understand the issue. Indeed, it’s an anomaly and currently the function only works if there is a single video clip present. But the good news is that I just fixed it for the next version 12.0.50.

Thank you very much)
