SMB1 still active in Bluesound

Have found various forum comments on the error:

HOST [IP.Address] failed to connect via SMB due to [SMB1 not permitted]

In my case this is from my Synology NAS log.  It is expected because SMB1 is disabled in the Synology OS.  I also deduce from forum comments that Bluesound disabled SMB1 some time ago.  However it appears that Bluesound is in fact still requesting SMB1 even though the Bluesound devices are successfully connecting via later SMB versions i.e. 2 or 3.  Yet, my log is filling with ongoing, continuous attempts to connect via SMB1, this indicates that Bluesound is still trying use this outdated and dangerous protocol.  Can you please help me understand what is going on here?
