RBR 850 guest network ssid broadcast

[saltiedawg]

My new Orbi 850 router set my guest network ssid to my network name plus "-Guest". When enabled, my guest network ssid would not broadcast. I removed the hyphen, left it as a space and then the guest network started broadcasting. Curious but issue resolved. The issue is when I disable the guest network and reenable it, it reverts back to the -Guest ssid. Anyone run across this?

Default SSID name for GN had the (-) dash in the name and works for me on my 7 series. Though I'm later version of FW. 
You might update FW:

If you do, Ensure you update the RBS first then the RBR lastly.

MIght do a fully factory reset and setup from scratch afterwards if yours still seens this odd issue.
