SMB scan fails with custom subnet mask

Is there a formal forum to post problems or a place to submit a problem ticket?

With 1.0.75, SMB scanning is ignoring custom subnet mask when looking for SMB servers. I have a flat network, using subnet 255.255.240.0. Have Zidoo Z9XPRO on 192.168.0.210. Have a couple of Synology NAS on 192.168.10.205 and .206. when scanning SMB, Zidoo only detects devices on 192.168.0.x? Seems to only be scanning 255.255.0.x, ignoring 192.168.1-15,x. All devices in my network are attached to dumb hubs, no VLANs, etc. Yep, I said flat. If I change Zidoo IP to 192.168.10.210, then it detects devices in 192.168.10.x, but ignores all others where 3rd octet is within subnet proper but not on same as Zidoo.
