Wavelab Elements 11 - selecting Bluetooth speakers

Hi everyone
New to Wavelab Elements. I am on Windows 10.
I want to have various sources to check mixes etc.
Over the weekend, I could go to audio preferences and click where the default ASIO driver is and my connected bluetooth speaker would show up. Today, despite having the speakers on and hearing them when e.g. playing something on Youtube, I just cannot get them to appear in the audio preferences drop down list. I have selected release driver, refresh etc - but nothing. I have quit, restarted the pc and the program but nope - just the default ASIO.
I have gone to the Control Panel tab within audio preferences as well to see if the speaker appears there but nope.

Any ideas what I am doing wrong?
Thank you

I’d like to know as well I’ve been having the same problem!
