Cannot hear the sound while I'm recording the screen, and a Bluetooth headphone is connected at the same time

I'm using ZDSoft as a screen recorder on Windows 10. When I connect my headphones using Bluetooth and start the screen recording simultaneously, the sound kind of gets muted. There's no sound anymore although if I stop recording and open the recorded file, the sound is good and all of it is recorded. So, the problem is that I cannot hear anything during the recording process. Here is my sound setup on the screen recorder application: I tried other options for Source 1 and Source 2 , but the problem still exists.
