Can not edit Customer name in new quote

[kmsgli]

I have just setup Gestion, thank you for this great product. I have setup a few test customers and a test product. When I go to quote the input field for customer quote does not show me any of my customers to select it is locked showing ---

It seems from that issue I can not setup a invoice because my quote is incomplete. Am I missing something here or is this a bug?

The system is Arch linux running latest releases of apache, php and nextcloud 28.0.4

Any help is appreciated, thanks.
