Frequent wake up packets sent from MBP to Mac Mini after 10.13.2 Update

I keep a 2011 Mac Mini sleeping, connected to my Time Capsule on 5Ghz. The Mac Mini runs the newest version of macOS (10.13.2 currently), 2.7Ghz i7, 8GB RAM, AMD graphics, and a custom Fusion drive (I installed SSD next to stock HDD and configured with CS).

The services I keep running on the Mac Mini are Screen Sharing, File Sharing, Remote Login, and Content Caching; along with iTunes Sharing, Back to my Mac, and Find my Mac. I also keep Mail and Messages running (picking up all my iMessages and SMS/MMS off my iPhone SE).

With all that running, I'm accustomed to the Mini darkwaking about once an hour for around a minute while it handles its crap.

However, after updating my MacBook Pro and the Mac Mini to macOS 10.13.2 at the same time, I'm experiencing frequent wakes of the MacMini, about every 4 to 5 minutes. I've traced this back to the MacBook Pro, because the two things that solve the problem are:

1) Turning off Wi-Fi on the MacBook Pro or

2) Turning off Wake for Network Access on the Mac Mini

Steps that don't resolve the issue:

-Turning off all sharing services on the Mac Mini

-Quitting all apps on the Mac Mini

-Turning off Port Forwarding (IPv4) on the Time Capsule

-Turning off Allow Incoming Connections (IPv6) on the Time Capsule

-Beating my fist on the keyboard and yelling bad words

The MacBook Pro is a 2015 Retina model, 15", 3.1Ghz i7, 16GB of RAM, IntelHD 6100 Graphics, macOS 10.13.2. They are both logged into the same iCloud account.

If anyone can tell me what I might be able to do to the MacBook Pro (besides turning off Wi-Fi) to get it to stop waking the Mac Mini incessantly, I'd really appreciate it.

Here's some info from the Mac Mini log that confirms that it's being network-woken every 5 minutes, and as I already stated, I determined it's coming form the MB Pro by temporarily halting the annoyance by getting the MB Pro off the network.
