Mac Vendor does not show upon first scan

**Describe the bug**
Upon opening Angry IP Scanner, scanning a network, devices show online. No Mac Vendors show. If I rescan, all Mac Vendors show.

**To Reproduce**
Steps to reproduce the behavior:
1. Open Angry IP scanner
2.Scan the network.
3. No Mac Vendors will appear until 2nd scan

**Expected behavior**
I would have expected the mac vendors to show up. Never had this problem in the past with Angry IP scanner. This happens no matter what network I'm on.
