For some reason, my laptop seems to have stuck in the Shared network with a (3) next to its name. Normally I have 2 macs: MBP (named OAMBP) and a mac mini (named OAMacMini). Something happened a few weeks ago, and whenever I go into share from any of the macs, I see a OAMBP (3) computer (see the screenshot). It's somehow stuck there, and no matter how many times I restart both computers, it won't go away. Any suggestions?
