Cannot record an overdub

Hello, my version of audacity is 3.2.1

I tried recording a guitar track and everything went good until I tried overdubbing my track. During overdub my voice is only possible to hear when the first track is silent. I searched the forum for the last hour but I haven’t seen that anybody has the same problem. In the file you can see the problem.

Thanks in advance

Check Transport > Transport Options > Sound Activated Recording.

If this doesn’t fix it, try Tools > Reset Configuration.

Thank you, it worked.
