Hello @Singtall,
It’s possible that on your Reverb FX send you are sending the return of the Echo FX.
I would suggest restarting all you sends. Select each FX send and make sure all faders are down. (On every layer)
Select your Echo FX and raise only your vocal channel fader.
If your Echo FX return is on unity at the main mix, you should then hear the FX on your main mix.
If you have further issues, kindly submit a ticket at our support centre and I’ll be happy to troubleshoot further with you.

Thank you,
Rafael
