False positive on OS detection with newer firmware on switch

I just recently deployed an Observium server to monitor the network.  So far it has been great and no issues adding devices.    I have a few Ruggedcom switches some with up to date FW and one that needs a FW update.    On the older FW v5.5 the device are discovered and added as a generic device.  With v5.7 Observium gives a false positive of a Wowza Streaming engine after what appears to be a re-detect.

o Re-Detect OS matched (wowza-engine: Wowza Streaming Engine):

I'm pretty new at this so hopefully someone can point me in the right direction on how to resolve the issue.   Attached are both 5.5 and 5.7 discovery debugs.
