Does anyone know how I can get a hold of Plex to file a bug report for this piece of ■■■■?

I can at least confirm and perhaps clarify a few things for you. When Plex finishes a recording, the play symbol appears in the Scheduled Recordings grid. The recording symbol displayed on an item means that it’s actively recording that item. The fact that you’re still seeing that symbol after the recording has ended is strong evidence of some deeper issue.
Also, I can tell you that I always experience conflicts when I open any HDHomeRun (HDHomeRun turner, Setup or Config) software while Plex is trying to use my HDHomeRun tuners. I’ve found that those conflicts don’t end until I reboot the machine that opened the HDHomeRun software.
Upgrading the HD Homerun firmware didn’t help, but I was able to resolve the issue. I was testing my tuner with the Windows 10 app. I was able to confirm the web ui is accurate for my tuner’s usage. That helped figure out the problem wasn’t with the tuner itself. I wanted to delete all data related to my DVR in Plex next. I noticed while I was poking around and found that the folder Plex created in the TV Show Library, “.grab” had some really weird permissions, different from the inherited ones for that folder. When Plex created the folder automatically is screwed up it’s permissions, the Plex users group I created had the correct modify rights, but the user account that was apart of that group had all of it’s permissions explicitly removed. This created a conflict in the NTFS permissions (I’m running Windows Server 2016) causing the app to behave wildly. After deleting the DVR I deleted the contents of this .grab folder, and corrected the permissions for said folder. I recreated the DVR in Plex and BAM! As you can see below the HD Homerun shows both tuners in use when I scheduled two shows to record at once.

I can also see in the activity log that both shows started recording on command.

Also as a side note the shows I thought it recorded the night before. It was only able to record about 30-90 seconds of each, and this eventually caused my live play back to fail, I am guessing that .grab directory is somehow used in the live streaming process. I noticed I had tons of trouble with live streaming around the same time as the recording problem.
I can also verify that Plex only complains when I am scheduling recording more than two shows at once.

As another side note. I’ve found that Antenna reception is HUGE to being able to record. From what I can tell any pausing due to signal loss, even for a second throws the Plex Transcoder into panic mode. I have to kill Plex server and delete the .grab folder to delete the partially recorded files usually. Sometimes it would still mess with the tuner count. I’m guessing the Plex transcoder service that is stuck endlessly trying to convert the video (thankfully not using CPU time) keeps telling plex it’s using a tuner. and that’s how I end up with one of my earlier screenshots where plex says it’s using way more tuners then I even have.
